The mobile market is incredibly different to the console market, though.
The console market is two or three firms competing by releasing major upgrades every 5 years or so. Each step is a large technological step which basically wipes the slate clean each time.
The mobile market, on the other hand, has more players and also evolves. A new phone comes out every 5 days rather than 5 years, so each generation affects the last in a way that doesn't happen in the console market. The result of this is that it will be much harder for Microsoft to take a significant market share like it did in the console wars.
