I don't think Nintendo is worried about this. They've found numerous ways to outsmart the competition. It isn't much of how much RAM you have but what you do with that RAM. If your company is smart enough you might just try to make your game playable on all current gen consoles. It isn't like PS, hard core games sold well on Nintendo consoles in the first place. The Wii had a short cut yet prosperous life with its first party software alone. I don't think at all for a second that Nintendo doesn't need 3rd party support but they rarely depend on it.
