Nintendo must have an ace in its hand

Neither PS3, nor XBOX360 will manage to pick up steam (in terms of both units sold and games released) before the next economy contraction occurs. So, it's going to be almost all game console marketplace to Nintendo (PS2 games would perform rather well, for those companies that would still make them). Just a thought... people out of work tend to lift entertainment industry, but the price should be right. The price of admission ticket to movies for family of 2-4 people is the right price. (And no, $400 for the device to entertain you is NOT!)

How did Nintendo manage? Was it a conscious calculation or did they just get lucky?
