What's great about this are the improvements make a good deal of sense.... in fact, long overdue. The Phase back "chassis" has long been in need of an upgrade, and its about time they did that. So welcome, yes.
What's disappointing is that they didn't take this opportunity to rethink their approach to the marketplace in any fundamental way - "its our upgraded back, here's our enhanced pricing" is the mantra.
That there is need for a rethink of the MFDB is (IMHO) obvious. But then again, their position is on top of a small, but obviously workable business niche. So maybe they don't see much need to change things. Too bad - a 33 MP back, with these features at $12-15k would be a good thing to shake up the marketplace....
They seem to have recognized some of this with their provocative trade-in proposition, the details which are still to come forward. Still, I wish they had pushed some of the other buttons - like platform flexibility (long overdue), better camera body, rotation.
