I dunno, it looks kinda cool. The front grip may also feel good. I won't make any positive or negative comments about that until I can mess with one for myself. The one obvious complaint then has to be the lack of dials. I can't believe I'm saying this but the physical controls seem to even make the Nikon 1 look pro-oriented. No PASM on a mode dial? Is that even a dial around the 4 menu buttons?
Um, unless you look at the fact that the newer modules coming out have APS-C sensors, putting a GXR with the A12 units or A16 units firmly in the range of most high end mirrorless cameras like the Sony NEX line. And yes, each module may be expensive but if you compare them to the cost of a good lens for another equivalent sized sensor cam they price isn't that bad.
Um, can you say strap that bad boy onto a helmet, under a gun barrel, or other places like that? Who cares where you focused when you can adjust that stuff later. It may not be the end all be all of cameras, but you could do some fun stuf with it.
Heck, if you could rig it to snap off pics wirelessly I declare it to be the best option ever to fulfill my dream of pig's eye view photography (snout cam, as I like to call it).
Call me crazy, but this camera feels like an intentionally inferior product. With the small sensor in an overly large (m4/3 sized) body, and with overly large but not very fast lenses, they can get people who just want the Nikon name on their new high end camera to buy a 1 series unit as an upgrade to a P&S. Then over time as they get more skilled with using the unit they start to notice the flaws... and eventually do the smart thing and get a DSLR.
Make the 1 series too good, tho, and you compete with your own entry level DSLRs, because those same people might be too happy and not need to upgrade.
