Well the Oly E-PL1 housing is now out.. in Japan anyway.
It does not have interchangeable ports... but it does have some very interesting specs.
There will be only two lens that you can use.. both zooms...seems they made the case to fit close to just them.
It appears to take 67mm acc... so wide angle and macro will be add on, by them or anyone else...
Looks like the case will be around $800...
There is a HD underwater video out.. absolutely amazing...
Olympus and Panasonic rumors
Down the page a ways.
I have to say, this may end up being the bridge camera between dslr's and P&S.
Meanwhile, the new Panasonic details are out... also pretty amazing and there are now sample video's and stills. At least the still samples are amazing quality...and with a 25mm wide angle, one may not need any extra lens.
Also zoom with video and .006 second shutter lag.
And given it does true 16/9 and can captrue 1080 images off of it's video, and has an underwater case...might be worth considering.

This looks to be a very good year for UW photography.
I really am liking the concept for the Oly...it may just be that perfect camera.. time wlll tell.
