Sony/SNE up sharply

Sony SNE is up sharply today (+4.02% at 50.47). I looked at the news and there is nothing to explain it yet. A short blurb about falling oil prices and the falling yen, but it is much to big of a jump for that. Maybe people are finally starting to figure out that the Ps3/BlueRay is really going to be a big home run? Just crossing the 50 barrier is good news at this point. Overall I'm up 15% on Sony.
