Doesn't appear to right now. That was one of the bullet points in the literature pre-release, but it looks like it was canned for the time being. I would imagine we'll see it at some point in CS4--maybe the next point update?--but I wouldn't bet on that horse.
Panasonic does have a transcode module for FCP, that'll turn AVC-I into ProRes422. You could then install the ProRes422 decoder for Windows (I guess I'm assuming you're on Windows) and edit those in PPro--the decoder actually works pretty well, in my limited testing. Granted, it's not a native solution, but a solution, nonetheless. RED and the beta importer might be the better option.
EDIT: Another option would be to download and install the demo of Grass Valley Edius, which natively supports AVC-Intra. You could transcode to whatever you wanted, then--like Avid DNxHD, for example. Again, not native--but what can you do? :)
