What TV have you used in the past for gaming?
I actually think the motion blur in game mode is one of the better ones I've seen (at 60fps), with the motion processing turned off. Better than any LCD I've used. I've never really gamed long enough on Plasma to know for sure, so it's possible those will still get better motion resolution for games, due to sample and hold.
Sony 65A1E, Marantz 5010, Polk LSiM 705/704.
