The reviews on MH Freedom Unite have started to come in, and if being a complete juggernaut in Japan isn't enough to tickle your interest, the American reviewers are hugging hard on this game too:

"It would be easy to boil this review down to, "Yep, it's just like Monster Hunter Freedom 2, but with more stuff! It's cool, so have fun!" And though that is true, there's more to it than that. Unite is a great game, and it's odd that Capcom waited until now to give the series a marketing boost in America, but there's also no better time to jump in and see what the big deal is. "
