Another GH2 or a G3 for a backup?

[bgpixelman]

I just returned from Bolivia after doing a documentary project. I will be going to Ecuador in January and this time I wish to take a backup camera. Chances are it may not even be used, but wanted one just in case of a problem. Should I get another GH2 or is there any advantage of getting a G3? The $200 or do so does not really matter. I have multiple batteries for the GH2 though.
I will be taking a Nikon dslr, since I hate the menus on the GH2 (I am primarily a still shooter).
Presently, I have the 14-140 and the 20mm 1.7. Will probably get the 14-45 lens too.
Any suggestions would be appreciated. Thanks so much!

Get a Gh2. Having the same body means same batteries, same charger, same format, same (terrible) menu. Plus I would advise to get a Novoflex adapter and use your Nikon glass on your Lumix. You will never go back to the stock lens except for autofocus.
