It is pointless.
Nintendo most likely started focusing games for the next system now anyway. They don't care if the system sells 150million or not. It has been their most successful home console to date and profitable from the start.
I know they will localise the games from Japan. Because it will be easy. They do not really need to work on anything else themselves. Also they have a zelda game coming out and kirby is yet to hit some places.
I personally rather they work on relations with 3rd parties for next gen.
They can always lower the cost of wii to $99 a few months before next console comes out if they really care about cracking records.
Listen to this man. He knows what he speaks of.
