Nintendo have been on the up for a good while now.
Unlike Sega that left the games console market and Sony that have had mixed reactions with the release of the PS3, Nintendo keeps dominating in every way.
You just have to look at the gaming charts to see how nearly all games are either DS games or games made by Nintendo.
The DS has been a huge success for handhelds and the Wii is following this trend for consoles. Shops are still selling out of them as they come in.
Pokemon, Nintendogs, etc as well as the amount of systems sold is crazy.
They certainly know what they are doing
