It's not that their being lazy with localizing the names this time around, it's just that since we can finally hunt together with the Japs(not counting MHXX) using a worldwide game, they probably decided it would be best to actually just make the English names similar to the Jap names, so as to not have that huge of a language barrier between the both.
