Probably not Microsoft. The X1X didn't do it the first year, I don't think making it cheap the next year will help.
If it is a new smash, and not a port(do we know if it is new yet? I don't keep up with smash) that is released during the holidays then probably Switch.
Otherwise probably PS4 with cheap deals.
