Nintendo didn't bundle the Rumble Pak, Memory Card 59 or the Expansion pack with every game that made use of it.
They will just release one or two high profile games with it and then the rest will require it but not be bundled with it.
You have the two EA M+ sports games with the bundle, you have Red Steel 2, you have WS: Resort and then Zelda (if it does in fact bundle, this still remains to be seen). That's more than enough games-two 1st party and three 3rd party- to distribute it enough. Maybe throw in one more bridge title from Nintendo and we should be set. Maybe the Retro project could be Nintendo's #3 M+ specific game since we seem to believe that they are now M+ experts according to Ubisoft?
