A nice and lightning-fast compiled summary on the product releases and previews can be found at the 1001 Noisy Cameras.
However, I am completely not convinced with the appearances of the J1 and V1, they look rather ugly and toyish afterall and the "1" logo makes them even uglier than they appeared! :-o

One unfortunate to note is that despite using a smaller 1" sensor than the micro-4/3's, the 1 bodies and lenses are not significantly smaller or lighter than the m4/3 counterparts! The late Pana X series lenses could be even smaller. So, another failed status given by me (picky person)! ;-)
