i feel bad cause no one has really answered him. OP, any of the canon dslr line isn't gonna be an upgrade from your 7d 9 (WAY TO GO QZYXYA, YOU'RE ACTUALLY RIGHT), i don't really have anything to suggest, but thought i'd give you a bump to maybe have someone who knows their video suggest something.
from what i have heard, gh2/gh3 really is that good for video purposes. i dont really know what i think about micro 4/3 cameras but just throwing it out there
