I'm curious whether this dips more into "remake" territory or an HD update...
The "it seems like they don't want to compromise the quality of the game itself" I said before was mainly directed at SQEX possibly taking this more than just a job of porting Type-0 and be done with it.
SQEX looks like it wants to make the game look as best as they can graphically, and using their strange logic putting the game on Vita seemed like a compromise to them since the release of this is mainly aimed for the Western market. Also, there is what it looks like another screenshot of Type-0 HD in a official Twitter page, and the screenshot while it doesn't show much it doesn't look like anything I saw on the PSP version (graphically I mean).
Personally while I know that Type-0 is a good game and all that I'm on a 'wait and see' with this HD version.
