Capcom: "MHW can't be done on Switch." But might make a Switch specific MH game. (Rumor)

This is probably the best solution and the most realistic one. It should however not be a 3DS style copy, but rather a from the ground up game which A: adds all the good mechanics from MHW and B: keeps all the good stuff from the older ones (IE: more monsters and more variations).
