First off, there is nothing confirmed yet for the system. Everything has been rumor and conjecture, so we still have no idea what the NX is. Secondly, Nintendo will be fine. They may have to go the way of SEGA, but unlike SEGA, they know how to make really good and creative decisions. They still have an impact and they still have a huge library of games they can fall back on if things go bad. As for your question: I have no clue. But never count Nintendo out, until they're actually out.
