Premiere Pro CS 6 and AVCHD - Should I upgrade now or wait?

Hi All

I currently use Premiere Pro 5.5.2 on a Mac Pro and OS 10.7.3. Most of my footage now is AVCHD, from various camcorders, including Sony FS100 as well as several Panasonic and Canon at 24P, 30P and 60P at 17mb/s to 28mp/s bitrates and LPCM and AVCHD audio. I also do use XDCAM EX and Canon DSLR H.264 footage.

I'm really wanting to upgrade to CS6, it looks fantastic, however I have heard reports of various bugs that make it work less efficiently or not at all with AVCHD footage. Maybe the latest upgrades fix these issues, but I'd like to get some input from people who have actually used CS6 with Mac OS 10.7 and AVCHD files. I don't want to transcode first, this was my primary reason to switch from FCP to Premiere Pro a couple of years ago, don't want to go back!

Thanks much for any and all advice you can give me.
