I've been playing my 360 on my Panasonic Plasma since I got it and I haven't had any signs of burn-in. Not even temporary image retention. I think a lot of it depends on the quality and age of the plasma. Olders ones were more likely to get burned, but any newer model you should be fine. Or at least any new, good quality one.
My copy of GRAW arrived yesterday. At first I was a little put off by the controls, but after about 30 minutes of playing I was loving it. The graphics are great, the audio is great and once you get used to the controls, they are great too. But the thing that I think I'm probably going to be spending my time on is the online play. The maps are great and huge and I didn't experience any lag at all during my play. This is a great game....especially on a big HDTV Plasma!
