I was reading though and a lot of people posted that they do not want to see the price go up if ssd was added, however ssd is still on a downward price trajectory ... and apple can buy large lots driving price down (especially if adopted in other mac lines (like the MBP). So ssd has the benefit of getting cheaper over time increasing apples margin, the hdd price's have basically flattened out.
Speaking of margin, apple has some room to play with because they already maintain the highest margins in the business. When compared to a base dell machine (I know, the specs aren't exact, but even when you max out theirs it's still only in the $475 range for their hardware).

Apple is master of using the hype machine to sell their products and could get the increased sales needed to make up any loss in margin, especially if they added ssd into their low end machine.
... The DVD slot will stay, as it is required to install the system.
As for the optical drive. I hate to see it go, but I can see it happening sooner than we like, Isn't apple already doing this? The air already has the system software on a flash drive:

And apple has their new software store on the way, movies can be downloaded via netflix, apple store and others. No need for optical for movies. Oh and if you feel the need, they have the usb optical disk they sell as an accessory for those that need it (
