We're 100% focused on World for western audiences. Yes, this is next main title! We have nothing to announce for Switch currently.

So it looks like MHXX for Switch only in Japan.  MHW for ps4/xb1/pc in the west and ps4 only in Japan. 

Wtf. I can understand wanting to expand in the west and supporting other platforms but they're just doing Nintendo fans dirty

I knew Monster Hunter World was the start of a new series of Monster Hunter games. AKA: There wont be a Monster Hunter 5

Pretty stupid decision by Capcom.I know I will sound childish saying this, it probably is, but I hope it bites them in the ass.

Capcom is such a miss and hit nowadays.They hit with RE 7, but then they go and do this.

I think you're reading too far into this, they said nothing about XX being Japan-only.

This is true too. Then I looked at op starter.._

So, when he says that they have nothing to announce for Switch, is just just referring to World? Or Western releases in general? I assumed that he just meant World.

MH will make it's way to Switch eventually, so I'm not surprised they have nothing to announce at this time

I mentioned this in another thread, but I feel that MH XX is basically testing the waters with a MH game on the Switch and probably will see how well it does first

So basically, they aren't gonna release it on the one location where it dominates... Weird

Does make me wonder where MH5 is gonna land though

Even if this is true.... It's region free :P
