For now I'll have to say 3DS only (I already have one).
All of the Vita games just look like games that I'd rather play on something else or are just not interested in. Uncharted? I already have U1 and U2 on PS3 and I'd rather play the games on there. LBP? Not that interesting to me. Bioshock! I'd rather play on the 360/PS3. I still haven't even played Bioshock 2 and I've had that for a long time now. SSF x Tekken? I'd rather play fighting games on a console with my joystick. MNR? Well I just got the psp one free (Sony's WBP) and I'm not really in any rush to play it. Wipeout? I already have Wipeout HD/Fury for the PS3. The size of the PSV is unappealing as well. Bigger than the monster PSP-1000? No thank you.
