We’re somewhere in the range of three months (maybe five) away from the arrival of the 2013 Mac Pro, which radically changes the approach to storage and cards: all expansions goes external, with Thunderbolt peripherals and USB3 being key to that.
What’s interesting is that I’m seeing a substantial uptick in interest in the proven 2010/2011/2012 model for the MPG Pro Workstation upgrade program.
And why not? The new model will be faster, but the existing model has proven itself as a stable workhorse. The new model will also demand a major investment in peripherals for anyone making the move, and it likely won’t come cheap.
Apple will almost certainly ramp down the production of the current model sometime fairly soon. It’s hard to be certain what this will do to supply, especially the 6-core and faster 12-core models, but I would expect these would become relatively harder to find.
