To me it looks like the best ISOs are 160, 320, 640, 1250 y 2500, much like it happens in the GH2 (although these look cleaner, but that might have to do with the compression even in the original upload file). You can even see that ISO 1000 is a lot noisier than 2500!
I think it performs really well considering the price (well, I've never complained about my GH2 performance in this department, really, as long as you remember the ISO trick).
What do you guys think? I'm getting one of these no matter what RAW cameras are out there!
