They did tried a Console MH a lot several times. World success is personally is based on graphics, proper marketing, and in a sense, Timing, as much as I dont like that Trend, Dark Souls really became meme for "its hard but its good" so calling MHW as "Dark Souls with Dinosaurs" was the right choice for some.
that being said althought it had a records breaking launch for Capcom, it also didnt have the legs previous games did (400K "only" in Q1 post release). but not that it will hinder its 10M goal given PC release has like several millions already is pre-order only
4 - 6M IIRC
