I rented a GH2 last weekend to test it out. If you're shooting motion only and will never take the camera off your motion rig (which better include a protective cage) I think it might be great. That's how I plan to use it, so I'm going to buy one.
However, if you want to use it is as a stills camera too or for any reason carry it without a cage around it or, you know, ever take it outside, buy a different camera. I wouldn't say I'd feel SAFE location shooting with the flimsy little D7000, but it's like a TANK compared to the GH2. It is absolutely the flimsiest little camera I've ever seen (not counting $200 point and shoots). My NEX5 is sturdier!!!
