At this point, I would purchase a GH2. But that's mainly because I've spent a few hours the past few days doing the research.
If you must go with the Canon, and you're stuck on the t3i...I would recommend spending the a couple hundred extra bucks on the 60D. It has a few extras and better specs that are worth the few more dollars you'll spend. And the resale value also holds up. There are a lot more t3is on the used market.
From what I found this week, I could sell my 60D for what I paid for it in April, but if I had purchased the t3i at the time, I'd have lost upwards of $300.
