This is a screen grab from a video in ENGADGET! Go watch it now, they MIGHT take it down ;) After all, this beauty is not supposed to be launch till next month! (As expected the video was taken down, but you still can watch it HERE.. for how long? Anybody's guess ;)
The rear of the new M4/3 beauty look similar to the E-M5, I like the thumb support with an "edge" where your thumb won't slide out :)
The new camera came with a really pronounced "grip", the handling should be much better than the present OM-D.
The E-M1 with the new more ergonomic grip and extra adaptor to mount a big 4/3 lens.
The new camera came with Wi-Fi and it is seen here talking to an iPad.
