If NX flops, the amount of money they have in the bank is irrelevant. It's the amount of new ideas that can make them relevant in hardware that's important.
The problem is, the number of competent executives that could turn Nintendo around in hardware is so small across the globe that Nintendo pretty much has to stick to the team they have. I think experience has shown that getting executives in competitor hardware companies to jump ship has a bad track rcord, so unless they are developing top executive experience from within there's not a lot to be done.
That's if NX is a flop. If NX is a success like Wii (for 4 years at least) and DS then there's nothing to worry about.
