I think everybody in their right mind agrees that the PS Vitas launch line up was way better than the 3DS's but the 3DS had no competitor so it got away with it. Vitas launch line up was good but the follow up was and is extremely poor. Two retail games in the next 3 months in europe.
About Metacritic scores, I have stopped to care about them since I own the 3DS since it feels like there is a certain hate towards the device from certain sites that are supposed to be neutral. Lately there are always some hipster websites that need to fall out of line in a really obvious way. Look at Kingdom hearts. The reviews gravitate around a solid 80 and then there is this one hate bomb dropping a 40. Same with Mario Kart 7, Kid Icarus and Destructoid. I can tell you that NSMB2 will struggle to stay at 80%.
Ongoing bet with think-man: He wins if MH4 releases in any shape or form on PSV in 2013, I win if it doesn't.
