I know nintendo probably won't be developing anything in house for this since it seems like they're giving out their ip, but if they made an mmo android/iphone pokemon game i would shut up and let them take my money.
I seem to recall an interview with someone on the Pokemon team who said that he didn't want to make a Pokemon MMO because he honestly thought it would ruin too many lives, although that story could just be apocraphyl.
Wow that's sensible and I really didn't expect that reasoning! If you look at IndieDB you can see that he's probably right because there are numerous unofficial Pokemon MMOs in the top lists. People crave for this!
