The biggest disappointment is the viewfinder IMHO.

12-45mm f/4

As much as love it conceptually, the price difference to the 12-40mm f/2.8 seems rather slim.

And what happened to the 150-400mm ...?

Well, you may not be able to buy it, but you can drool on the picture of it here:

It is big, but big & beautiful!
