I can't help but notice that no one is talking about how they might still be able to get one of these. I held off a bit too long on ordering the MH4 bundle. Does anyone know if they may ever come back in stock?
At this point, nobody knows anything for certain - so keep that in mind.
However, there is a distinct difference between the MM and MH systems - it has been confirmed (by both Gamestop and Nintendo) that the MH system is truly limited and retailer-exclusive; at this point, the 'limited' nature of the MM system is still very much a question.
Consequently, I would imagine that you would have a MUCH greater chance finding a MM system at release (or perhaps via preorder, if more open up). Based on Gamestop's past record of limited system preorders, and the fact that the MH system was live for ~2 days (leaving plenty of time for non-scalper buyers), I'd say there's a good chance that there will be no additional stock. Heck, none of the MH system that were ever available to preorder were eligible for in-store pickup; all were ship to home.
