Ok people i think we should stop the fighting between the members and use the efforts to do some more speculation about the possibility of the MBA @ WWDC.
In my opinion there are 2 scenarios:
1 - Major update with possible case redesign. If this happens there will be one breakthrough feature that will set the MBA appart from the MBP and make it worth use that precious WWDC time.
2 - No update at all. Apple will not introduca a minor update @ WWDC and I am almost sure about this for the simple reason that they could have done that together with the MBP in April. They were upgraded together @ 2009 WWDC and they should have been upgraded together in April. This makes me think that it will either be BOOM MBA or nothing.
I feel like there are far more than two possibilities at WWDC.
I still believe it's possible to get an MBA update with C2D and Nvidia 320m that is a quiet update and includes larger SSD option and 4 GB RAM.
It completely made sense for Apple to update 13" MBP first. Then, it made even more sense to update the MB as the "Back to School" promo started this week.
It would not be impossible that the MBA was just last of the Mac notebooks to get the same update as soon as the inventories of 13" MBP and MB could meet demand. Then the MBA would go to production. A C2D MBA with Nvidia 320m isn't going to warrant an update at WWDC and it still makes the most sense to me. Apple is all about this MacFive strategy. I also see the Mac mini and 21.5" iMac getting updates with the Nvidia 320m strategy. Surely Apple will get the MBA out of the way first or all of these together maybe as a quick announcement at WWDC or even a quiet update the week after WWDC.
Now there's also the possibility of Apple introducing an MBA that is exactly the same case and C2D and Nvidia 320m at WWDC but they're adding one new service offering with it. This would happen if Apple has something else to introduce added to it. I still believe the Verizon partnership has to start somewhere and a 3G/4G LTE Verizon card could find its way into the MBA first to "test" the waters so to speak. It's also possible Apple partners again with AT&T with its new $25 2 GB service without contracts on the MBAs with a simple 3G card added to the MBA.
Then there's also the possibilities that were previously mentioned by you as #1 and #2.
I feel that there's a lot of hope here. I really think it makes sense to put the Nvidia 320m, along with 4 GB RAM, and larger SSD in the MBA now. All of us MBA buyers would absolutely jump for an MBA that just had more RAM and SSD. We mostly feel the Nvidia 320m is amazing, and C2D does the job just fine.
There's also the idea you had (#1) of a major update to the MBA at WWDC. It makes a lot of sense to prove that Apple still gives a damn about the future of the Macs. The MBA is the most portable/mobile Mac that runs OS X. We all know it's a different market than the iPad anyways (whether all agree with us or not is unimportant). Apple could amaze us with a Core i7 ULV overclocked with a discrete option, or a LV Core i7 with sole use of Intel's GMA (probably more likely than discrete). A major update to the MBA's case (like carbon fiber) might make sense too, as Apple can see what the reaction is to lighter weight Mac notebooks via eliminating aluminum.
Apple could also do something really innovative that none of us can calculate. I feel like an LCD/iPhone like trackpad integrated with the Macs makes a lot of sense. They could also use the MBA to introduce a new cooling technology as their patents describe. They might even be able to fit LV and discrete chips in the MBA if they could cool them. They might have a super battery, or they could be a touchscreen display (although I completely discount that personally, but some insist). I even think there's the possibility of an OLED or 3D display in the MBA. Apple could leverage its LG partnership and introducing a 13" display is a lot cheaper when mass developed than 15" and 17" displays required in MBPs. Maybe it's just an IPS display in the MBA first.
Finally, it all comes down to the MBA being an ultraportable AND a LUXURY Mac. Apple can do just about anything and test the strategy with the MBA. None of us knows whether it would be ready by WWDC or not. There is something to all the MBA rumors, but we don't know what it is. Could be minor update day of WWDC along with Mac mini and 21.5" iMac. Apple could do that and introduce all as a quick note after introducing a new Mac Pro.
The important thing is Apple needs to be incredibly innovative with at least one Mac update at WWDC. It could be the Mac Pro. But no matter what, I have to believe something is coming. Most of us realize Apple is about mobility and it's going to leverage its OS X position along with iPhone OS products. There is no reason not to have an incredible MBA that competes along with ultraportables and luxury computers just as the v 2,1 MBA was innovative and future tech when introduced in October 2008. Apple knows how to make a killer ultraportable. And it could provide just about anything it wants because it will just raise the price of the MBA to offset the tech costs.
We have five days... actually 4.5 days remaining until WWDC. I just hope we're all celebrating and crying tears of shear joy after the announcements. As we are all enduring the long wait for an incredible new MBA... or even just a simple update with 4 GB RAM, 256 GB SSD, and Nvidia 320m. Believe me, they will be tears of joy whether it's a big update with discrete GPU and two RAM slots or 4 GB RAM and an Nvidia 320m. We know we're fans here... no criticizing our wishes for WWDC.
