Nintendo's First-Quarter Profit Rises Fivefold on Wii, DS Sales

[Bodhesatva]

This would average out to approximately 2.5-3 billion in profits, for the fiscal year, depending on the Christmas sales.

The entirety of Microsoft made approximately 14 billion dollars in profits last year, so about 4-5 times this amount.

The entirety of Sony made 1.5 billion last year, so Sony's profits as a whole would be about half that of Nintendo.

Are any of my numbers and estimations incorrect?
