Indeed I am! I just pre-ordered it today, in fact! :)
Ah, any Rathian is a favorite of mine, so the more the merrier! I'm just a sucker for pink in general, haha. Though the Dreadqueen variant looks like a gorgeous terror, and I'm sure it'll rank as one of my personal favorites once I get the chance to slay her myself. ;)
What about you - you getting MHX too? How long have you been playing the series?
