I don't usually get hyped for remasters but I absolutely adore this game so I'm pretty damn excited to get a modern version. Hopefully it does well enough to justify a proper sequel (because MediEvil 2 was kinda balls).
Never played the sequel, but from what I know it reviewed better than the first game and seems to generally be held in high regard, so your comment surprises me.
Anyway, best case scenario is that this is a full-scale remake of the PS1 original, with all the necessary changes made to help it meet a current-gen standard.
Worst case scenario is that it's a standard remaster of the PSP game and nothing more.
Please please don't be the latter.
