I have a 42" Panasonic plasma and I am picking up a PS3 next weekend. I also plan on also picking up Grand Theft Auto IV and prob playing it for hours on end. Anybody think I'll have problems with burn in. Right now I play a decent amount of Guitar Hero and havn't seen any evidence of burn in. Some slight screen retention, but it goes away quickly. I don't think this is gonna give me a problem, but wanted to check with the experts before I decide to stay up till 4am playing GTA IV.
