Everything could be, but I don't understand why they would present a redesigned 55mm wide to accompany the new camera, unless it is the standard lens to accompany the camera.
A wideangle would make sense if it would be a very wide angle to compensate for the reduced sensor... like a 28mm...
I strongly believe that we are are going to see a "more-than-full-format" camera, with a sensor just a little larger than 24x36 (like 30x40), a format similar to Canon or Nikon pro bodies and the 645 bayonet. All that for the cost of a Nikon D3 and around 28-30 megapixel.
Ater all, why should they cram 14Mp in an APS-C format sensor if not to test the resolution for the "FF-plus" marvel?
