I have a plasma and burn in rarely occurs on newer plasma tv's, if you mean image retention then that is different unless you're using an older plasma without the image jitter option. However, I have played games such as Dragon Age for hours on end for a few weeks straight and never received a burn in, image retention yes but never a burn in so in regards to the power bars I am assuming they thought about that when making the game & probably came to the conclusion most people are playing on modern day plasma televisions.
