I hadn't realized what the poster earlier noted about the Yen, he's right about what he wrote. If the Yen is still around 87 per USD in the third week of January, Nintendo and Sony should end up with higher profit margins than they expected.
For what it's worth though, Sony did lose over $2 billion in the December 2011 quarter. Sony isn't really a holiday oriented entertainment company. Most of their blockbuster movies come in July for the Summer movie season if anything, music is unreliable, and Sony doesn't have an internal hit like Mario that can sell 10 million copies on cue during a Q4 to drive profit up.
Sony lost 42.5b Yen from April-Sept 2011, and then it expanded to 201.5b Yen in April to December 2011.

Sony did profit $893m in Q4 2010 though.
