NX conceivably being both a handheld and home console plays off extremely well for an HD port of Monster Hunter X.

Let's acknowledge something: Monster Hunter has a DIEHARD and growing fanbase. Many of it's fans put hundreds, even thousands, of hours into it. Even if Japanese players are playing it already on 3DS - many will very eagerly go for an experience that's on an HD portable.

For western players, Monster Hunter X HD on NX would likely be their first chance at getting the title - which would make it a very promising launch exclusive. If it can garner the same or greater attention M4U did on N3DS, it can help set off a narrative that NX can be a system with strong 3rd party support and an active online ecosystem. This was probably the intended effect of MH3U on WiiU - but the western MH community hadn't grown enough yet and the network features at the time, especially for the portable, weren't strong enough to create the same bandwagon MH4 & MH4U had. All told - Nintendo and Capcom now know a lot more about how to get this franchise really, really right and NX launch seems like an obvious opportunity to take advantage of that.

We've talked a great deal about EA, Final Fantasy, and Zelda on NX this past week - but I figure I'd stir the pot even more about NX and MHXHD. Just shows you how promising the NX could be, right?

Didn't the Wii U launch with Monster Hunter 3 Ultimate in japan?

Oh brother... there wasnt heven a MH4 HD, why would there be a MHX?

That would be amazing, it would boost the sales in Japan that's for sure

I always did think that Monster Hunter on NX launch would be a dream come true. I really want MH5 to come to NX too.

There is a decent chance that there could be a Monster Hunter game as a launch title... whether it's X or not, I have no idea :p

Monster Hunter makes me sick now. To consider such a Sony thing Nintendo... It makes my stomach churn.

Didn't stop me from getting that sexy ass 3DS, though.

It's not a Nintendo thing. YAAAAY! :P

Except the last main, non-Frontier title to release on anything but a Nintendo system was Portable 3rd on PS3 in 2011. The way the games are made, there's no reason that can't appear on Vita as well. The bottom screen is useless anyway. 

Now that you mention it makes sense smart idea and would make both ninty and capcom happy.
