The only reason that Nintendo would want to quadruple first party output is if third party wasn't on board. Otherwise, there is a much much higher risk of franchise fatigue with their iconic heroes. It would be reasonable to assume that she's talking fluff, or that we will have yet another Nintendo console with minimal third party support.
Edit - given the circumstances, I'm leaning toward her over exaggerating. I suppose a third option would be Nintendo merely seeking to rev up their creative juices and begin a new IP campaign.
