From what I've seen, it's sold quite well. Servers were 42.2% of maximum capacity shortly after launch, and the 3DS version is among the top 5 best sellers of the week from Gamestop (at least in Canada). This means that both versions of the game sold well upon release.

I don't think Capcom/Nintendo are expecting earth shattering sales for the game, but for a localized Japanese action game with a cult following, this particular title has made quite a name for itself.

Not to mention, the game has been garnering favourable reviews from most outlets, with huge western sites like IGN giving the game a lot of praise. This is sure to provoke newcomers and strengthen the sales base.

Honestly, I think we have nothing at all to worry about in regards to MH4 being released over here. MH3U is already more popular than MH3 was both upon its launch and in the weeks and months leading up to it. If Nintendo was willing to localize MH3 after MHFU's not-overly-impressive sales, and willing to localize MH3U after MH3's moderate sales, then it stands to reason that they will happily localize MH4 given MH3U's considerable sales.
