This rumor holds some credibility as the same guy who leaked Monster Hunter World is giving us this information:
From the GAF User:
I don't think they will come around and localize this. By the time World is out development on a new MH from the XX team will probably have started. I think it's far more likely they'd focus on localizing that to keep the series going with worldwide launches than look backwards and localize XX.
MatrixMan.EXE: It's already started. Capcom's Monster Hunter teams are really stretched right now.
So we can hopefully stop the, Capcom isn't supporting Switch drivel...please?
