Anyone getting worked up is jumping the gun.
All we know is that there will be figures, and they will have the potential to interact with multiple games. We don't know what type of games will be involved, what the pricing or distribution of figures will be like, how figures will interact with games, or what costs will be. Without more information it's kind of pointless to make any serious comments.
That said, I'm more worried about how hard it will be to find/buy figures without resorting to second-hand scalpers than about what the games are like. Hopefully NoA does a better job supporting this idea than they did with other game-related items like Kid Icarus AR cards or Animal Crossing trading cards. (Should be different due to profit potential... but NoA hasn't earned much confidence from me in how they handle product releases lately.)
