Thought this was interesting and thread worthy. Yuji Naka in a recent interview with Famitsu: Naoto Ohshima added: Source: http://nintendoeverything.com/yuji-naka-still-wants-to-see-mario-and-sonic-co-star-in-an-action-game/ I remember back in the GameCube days which Naka references there was a strong rumour of a game entitled "Dreams Come True" presumably named after the band of the same name that was supposed to be the title of a Mario and Sonic action platformer crossover game. Whilst Mario and Sonic have teamed up for the Olympic titles a proper action game starring the two seems a distant dream at the moment. However it's interesting to learn that Naka pitched to them and according to this interview wants to pitch to them again. Pretty lovely news if something tangible comes of it in the future. Good luck with your new pitch Naka.
