Apple has announced the WWDC, or World Wide Developers Conference for June 10th-14th.
This would be a perfect place to announce a new MacPro as these are Developers, and this has been a venue in the past, though Tim Cook in his recent call said that they had new things for the fall.
Honestly if there is no MacPro announced at the WWDC, it is time to start thinking of moving to PC, as I just can’t trust in Apple anymore. And they have had years to work on a new MacPro and the current model currently can’t even be sold in Europe! They need a new model and it needs to be before the Fall (if it is even then, as all we know is that Tim Cooke said something about a new MacPro this year).
The only thing that gives me hope are the new video cards, the NVIDIA Quadro 5000k and the GTX 680 being released for Mac.
