The very very best part of this port of the game would be the 60fps, as the original game ran at 30... but would it run at 60?
If this is a remaster, perhaps a different developer would be putting the time and effort into doing whatever patchwork is necessary to have this game run in a stable state at higher frame rates, like what Bluepoint did for MGS3, if it's a simple port such as the recent port of Bayonetta, then Platinum could be doing it themselves. Considering their recent fairly basic ports it begs the question, if the game doesn't easily run at 60fps, would they be willing to put in the additional work necessary, or would it be another Dark Souls? I think most of the cutscenes were pre-rendered so they'd probably get away with leaving those at 30, but are the animations and effects in the game 30 too? Do they need reworking to match the refresh rate?

I love Vanquish and i'd love for this release to be flawless, at around 6 hours long it's not a meaty experience, but in an era where it feels like most games take 20+ hours to get through, a quick visceral shock to the system is more than welcome.
