I kind of agree and disagree with your points. I understand where you're coming from when you say that it shouldn't be obvious what is a 'main' game and what is a portable version, but it hasn't always led to bad situations.
I mean, example: Ratchet & Clank: Size Matters (PSP) is the best-selling R&C game out there (even more than the heavily-bundled-in-Japan-original-game). Daxter is the highest selling Jak & Daxter game. I also think God of War: Chains of Olympus pulled really respectable numbers.
Even though all of these were spin-offs, they were handled by incredibly talented "B-Team" devs (Ready at Dawn and High Impact Games), and I have no problem with that. In fact, I think it's a really good idea, because it's the kind of thing that will make fans of those series (like me) buy a PSP/Vita to play these games, and it will let new players (with no knowledge of the IP's) jump right in because they are spin-offs. Clearly Nihilistic are less talented devs than those other two studios, and it's causing a bit of a problem.
Maybe the solution is simply to make spin-off series for the Sony portables, but not so that it seems like it's a spin off. Say for example - Uncharted. If Golden Abyss 2 came along next, that makes it seem like it's simply a parallel series to the PS3 games, and that's probably a good move.
I think the future looks bright for releases too. Sony Cambridge handling Killzone Vita with help from Guerilla seems like it will be good, and LBP Vita have xDev on board, who should keep the quality up. I'm sure Sony Bend are working on something good now as well. I hope High Impact Games get hired again to make new Ratchet/Jak games, because I genuinely believe they did a stand-up job with the PSP versions.
Was interesting to read your thoughts on this though, so thanks for that :P
