Well, I don't believe in Microsoft either, so I don't think that outselling the xbox is any accomplishment to be proud of.
You could say things like "the Wii is the weakest market leader ever, with less than 50% marketshare", or "second place is still quite good", or "they still sell better than last gen second and third place consoles".
What really matters, is hat both of them are horrible financial failures, any smaller company would have already gone bankrupt from them, they are very, very likely to end the generation with total numbers still in the red.
If no for their competition that showed that there is still room for expansion and profit, video gaming would be seen as a rapidly shrinking market. The only reason why they might try to enter the next generation is that they will try to be less suckcessful, and they might try to get a part of that new audience.
