From that perspective, yes, it's a good ideas, seeing as they're doing the same with the Oculus Rift.
What I don't get is the way they're launching 5K. They're forcing you to purchase a fairly expensive machine that doesn't have the specs to back it up, regardless of the screen resolution. If they had a range of different options for 5K, including just a monitor, that would be fine in and of itself, but they've instead opted to do their traditional dictatorship over the hardware, and I think that's going to limit sales.
