Why are people getting so overhyped about it??

N3DS is region-locked and most unfortunately MH3 G is very unlikely to be released outside of Japan.
If Capcom is making wise marketing decision,they would have localized MHp3rd already and MH3G should have been ported to PSP instead.4.4 million copies sold doesnt lie.

You'd better be begging anf praying that Capcom will decides to localize MH3 G otherweise you will have to buy a Japanese N3DS just to play it.And MH 4 isnt gonna come out anytime soon.
