I would say Nintendo will be prepared to launch first, but it will depend on how their sales go and how desperate the competition is to try to get a better selling system...
As long as Nintendo can never make enough wiis for people to buy, they will delay the release of their next gen system., even if Sony and Microsoft release their next gen one...
If sales slow quickly and a price drop doesn't help much, I am sure they will be first.
If they release too soon, they will just make their customers unhappy for be obsoleted so quick!
