on the second brawl trailor when it shows fox ..theres a short battle scene where the stage has two levels...look closely it looks like fox is fighting falco on the second level platform..one of them shines and i think an up air then they fall into the first level platform...after that i think fox does a dash kick towards falco...but i dont know ..maybe..just a thought check it...http://youtube.com/watch?v=nHNjFeTzIO0&mode=related&search=
