Not to mention the fact that you look at pretty much any behind the scenes video from a high-end photo shoot and you'll see it's about 70-90% MFD being used, despite what some people here like to think. My only complaint is that we're now on the second generation IQ-series and still no real new camera in sight.
Just because today's announcement is for new digital backs doesn't mean it's the only thing Phase One is working for (no big surprise here, considering the CEO already publicly announced they are working on an entirely new body).
However, if you haven't used the DF+ you should give it a whirl: it's significantly more improved IMO than the "+" would indicate.
O, and in case there was any doubt the IQ2 will come in all the standard mounts: Mamiya/Phase, Hassy V, Hassy H, and Contax.
Something about mixing an IQ2 with an iPad on a Hassy 500 seems very steam-punk to me.
