I voted for the Sony F3, through I'm an obnoxious GH2 fanboy.
I've never even held an F3, but I've dreamt of it.
The new Nikon D4 promises much, it's the only large sensor camera that does 4:2:2 color that price point ($6,000).
F3 is Blah. But kinda into it for lowlight. Not too heavy, not too light either, build it out and it's as big as a RED MX, but less quality? Just had one in my hands actually... was randomly shooting with it out of boredom. S-Log is pretty.
D4 looks sweet, we have one on order. Not sure if we're gonna cancel or not before we have to pay for it. If we keep it I'll hook up the Samurai and Ki Pro (gemini if it FINALLY comes in) and see what the image looks like. Not expecting gold, but eh. Full Frame = sweet.
C300 is what I'm waiting to get my hands on. Hoping the US betas start going out, will try to get one early to shoot with.
Definitely a GH2 fan (but you know that. xP) Had an FS100 a few weeks before launch, it was fun to play with and an interesting design but I can't stand the way the highlights go so fast, and the mushy image at high dB of gain. Just not a fan of it...
AF100... nothing needs to be said beyond it pisses me off royally. Love how light it is, built in NDs so on and so forth but the GH2 murders (w/hack) in image quality land. Selling three, anyone interested?
F3, FS100, AF100 -- playin'.
