I remember hearing/reading/watching an interview where he basically said the same thing. That it would be cool to have special moves based on classic tagteam setups. IE subzero and scoprion, kabal and kano, RAIDEN AND SHAO KHAN OR LIU KANG. it looks to me that the magazine printed this as new but this is definately something that has been spoken on before.
If that's indeed the case, then it would have been before Boon implied that bosses would not be playable/stated that Goro would not be playable (and if he isn't then it's logical that no other boss will be either). In which case, I'll take his most recent statement over the one in this thread.
