I'm guessing that Apple will at least announce a new pro computer at the their next WWDC which will probably be in June 2013.
Not likely for several factors.
1. Intel will refresh the laptop CPUs to Haswell earlier in Q2 2013. The Mac laptop line up will be done for a refresh and the MBP 13" is desperate need of a faster GPU. That will be top priority for WWDC.
2. The Mac Pro upgrade is already horrifically late as it is. Waiting till WWDC to "fix" that is not a good move. The other problem is the WWDC is already a logjam of Mac updates. It occurs right before the OS X update window which is additional bad timing.
3. Throw on top that the iPhone, iPods,
and iPads have all shifted to Q3-Q4 basically empties out Q1 and early Q2 of everything. It is actually a very good spot for the Mac Pro. No distraction with other stuff. About 6 months after OS X update so the minor version bump for the product should be far more stable overall.
4. The desktop GPU update cycle refreshes around late Q4 through early Q2. Apple can catch appropriate GPUs around the time they update. (presuming can get get drivers to roll out on time).
5. Not that Apple should be waiting on Ivy Bridge Xeon E5 they are roadmapped to appear in the Q3 ( after WWDC ) timeframe. If would be far better to get something out much sooner to that can upgrade to Ivy Bridge models either late Q4 2013 or early Q1 2014.
The Mac Pro doesn't need a huge Apple "dog and pony" show. Apple needs to demonstrate that they can consistantly get upgrades out the door on a reasonably predictable schedule. No hyperbole filled stage show can do that. It is about doing something, not talking.
The steady state Apple is probably heading for is
May-June Mac portables refresh
July OS X update
August-Sept Mac mini and iMac refresh
Sept iPod / iPhone
Oct. iPad , iPad mini
Jan-Feb Mac Pro ( while still has customer buying support ).
[ maybe an iPad max if that ever shows up. Apple TV and
Airports could go here too. It is "hobby" time of year. ]
If Intel moves their Xeon E5 class updates into the second half of the year. Then parked at Q1 the following year Apple can consistently pick them up and move forward ( along with a new GPU card ... presuming they stay on their Q4-Q1 update window. )
Will the entry model start at $2500 or will they be more scalable to be competitive with PC boxes.
100% unlikely since the price doesn't end in a '9'.
