I think that the fact that the PS Vita will not be released on 2011 will give Nintendo the opportunity to sell an excellent amount of units and games. I just hope that Sony doesn't have a plan in it's shoulders.
There is a high possibility that those will be the free games on Sept. 1st, although Nintendo did say that those games are tentative and are subject to change if needed.

I agree with Brightside. Nintendo shouldn't invest for cash on addons to games. I am not very interested in that. However, an achievements feature with rewards would be a great idea. Users will want to play the game more often to complete them.
