The fake Mac Pro Upgrade left a lot of professionals speechless as they were all waiting for Apple to show that the professional market still matters, and instead of an upgrade, there was almost nothing.
According to David Pogue, who is often well informed, the Mac Pro is not dead, new models are under way and will be released in 2013. Same thing for the iMac.
It's not much but it's probably enough to give back a little bit of hope to all pro customers that fear the disappearance of the Mac Pro, especially if you add to that the answer that Tim Cook provided to a worried customer who inquired about the Mac Pro:
Our pro customers are really important to us...don't worry as we're working on something really great for later next year.
Therefore we will have to be patient before we can see the new models coming out, and we hope that they will be as revolutionary as the other products. It's probably safe to bet that Apple is working on the design as well as its strategy regarding the Mac Pro.
There are many things missing on the Mac Pro that are widely available on the PC side like a real multi-graphics card GPGPU, efficient RAID systems,etc.
For now wait and see. What we'll want to see is whether these future models are revolutionary enough to get back the many professionals that went on the other side and chose to work on high performance PCs because they were tired to wait.
