FF would be awesome, but it would just be big and expensive, but I would love to see something go against Leica.
I'm guessing it will be C size with a new mount. All I really care about is if it can fit into a (coat) pocket, with a prime pancake.
Now I just can't decided if I should wait for this or pick up a E-P2 w/ a 17mm on it, there are some nice deals on ebay.
