I'm sorry, but no, the port is not fine at all. It shouldn't even have been released in that state. This isn't obsessing over the detail in water or some missing special effects, the PS3 port runs significantly worse to the point where it effects gameplay frequently (and although it's relatively minor compared to that, the washed-out look does not help the game at all). Maybe it's not as clear on Easy, but if you're going for 100% completion you'll see how bad it is (although I don't know how you could have missed some of its worse moments even at that level).
Yeah I did go for 100% completion (PS3 died half way through infinite climax) and I see none of these so-called gameplay affecting problems. It ran fine, maybe not as well as the 360 version, but minor detail loss and loading times don't affect the game that badly.
no here's what would REALLY rule and won't happen: if every enemy in Vanquish actually had a fully developed melee moveset that they would only really use if you play as Bayonetta (and, of course, the ability to play as Bayonetta) so Vanquish would simultaneously be (functionally speaking) Resident Evil 4-2 and Bayonetta 2
Yeah, Kamiya said that because he hates the concept of dlc apparently and because they stuffed the game with so much add-on content from the get go already. But it's also like SEGA's only really successful game recently (?) Especially when it comes to critical acclaim.
As long as the PC is basically all but a joke in Japan, and commonly viewed as a "Pirate's Paradise" every where else, that's likely going to be the reason why a smaller developer like P* likely won't have many (if any...) PC ports. Such a thing is just a money sink for them and their publisher.
Any way, it will be interesting to see what else they could stand to do. Besides the "Cutie J" idea, I could definitely see Kamiya's "Umbra Fighter" come to life.
