I am not sure if it is just the DF+. My feelings are unless the new back is 16-bits and they provide a new camera that can compete with the features of DSLRs, this IQ250 will fail.
A new camera is coming, but I kind of feel the announcement would be at Photokina. Or maybe Hassy's announcement is forcing them to release it earlier than this Fall.
Guess we will see tomorrow.
