Ignoring the western 3rd party support discussion since that's not going to happen...
I do have to say that I think people are a bit disillusioned about the western support the psp got. Go look at the psp game list here on Vg. Other than sports/racing games You'll find only a couple of big western third party games in the entire lifetime of the psp.
The difference is the PSP got Capcom, Square Enix and Konami support. Games like Metal Gear Solid titles , Monster Hunter titles , Final fantasy Crisis core, Type-0, Star Ocean titles, Dissidia: Final Fantasy , Kingdom hearts titles, Final Fantasy Tactics, Winning Eleven titles, Dissidia 012 , The 3rd Birthday, Yu-Gi-Oh! games, Castlevania titles , Silent Hill titles, Coded Arms etc.... These are all gone from the vita library.
Anyways, the problem I see with vita indies is variety, there are only so many 2D games I can handle and I say this as a fan of 2D puzzle platformers/scrollers/Metroidvania titles etc... Get Bastion, Torchlight 2, newer titles like Outlast or multiplatform releases of upcoming titles like Transistor and Secret Poncho on the vita. i release most of the titles I mentioned are Top down RPGs, but that's what I want :p
