Jonny Evans has the big picture around Apple’s 4K Mac Pro plan (which I’m sure Apple executives were willing to share):
Mac Pro will ship in December. It is likely Apple will offer 4K displays made by Sharp for sale through its stores when the Mac goes on sale.
What about 4K content?
Mac Pro, Final Cut and other 4K-compatible software tools in conjunction with the emerging Thunderbolt 2 class peripheral products that should surface in 2014 mean pro content creators will soon be in position to affordably create 4K content.
That 4K is the future is not disputed, but it’s an expensive future. My bet is that Apple will have a 4K Thunderbolt display to match the Mac Pro in 2014.
