Front speakers for articulating wall mount?

In trying to make the best of an awkward room layout, I have decided to mount my plasma to an articulating mount. It will be in one position for movie/TV watching, and moved to another position for gaming. The movie/TV watching has it at a 45 degree angle away from the wall. What do you recommend I do for front speakers? Should I get ones to mount directly to the plasma? Floor stands and move them when needed? Any help is appreciated.
