I have a Pioneer Elite Pro-1130HD plasma. I Really like it. I use it for everything form Tv, Movies, and Games. I havnt had any burn in problems. I have had some retention every once in awhile. Like when i was playing Zelda Twilight Princess for wii. The only time I noticed it is when you had a bright white screen. But the Retained imaged did go away over time. Id say it was completely gone within a few weeks. Even games Like Metroid Prime Echoes with its full HUD display on never left any burned in image. There was one day I played Zelda for 11hrs. With no problems. So really I dont think there is much of an issue with burn in with these sets. Just dont watch CNN or QVC all day long. Those situtations may give you burn in. The thing is if your going to fall asleep just shut the tv off. The Kuro Sets are great.
