Sell! Sell!
No, this is great news for Nintendo. Things aren't all rosy, so when they can get a new market and shore up investor confidence with little effort, that's huge for business.
PetariJ, the rumors come from a recent statement by Iwata. I don't have a link, but he was vague, saying Nintendo is looking at things like mobile and changing its business model. No specifics, no plans given. It could mean anything from dumping home consoles and making a smartphone to just changing the way they spend their ad budgets. Who knows. Nintendo probably doesn't know either, so when they can buy some time with things like the Chinese market opening up, it can keep them from making any rash decisions that'd cost them more in the long run.
