Well, considering the fact that most titles on either system is exclusive, and rooting for one but the other means that you'll miss 50% of the good games. Hence my owning both. Seriously, you can't play Megaten IV on the Vita and Persona 4 Golden on the 3DS, so there is no way I'm gonna choose between these 2. As for "suprassing," no. Good games are coming out for both systems simultaneously.
