Nikon D7100 will kill Panasonic GH3

Reasons one could have for buying a GH3 over a D7100

1) EVF (yes, alot see this as an advantage, including me)

2a) Broadcast quality movie codec

2b) 1080p60 video

3) Arguably better selection of prime lenses

4) Ability to use wide range of legacy glass

5) Swivel screen

6) Smaller and lighter (especially when any sort of lens kit is included)

So no, I wouldn't have said the D7100 will "kill" the GH3.
