There have been plenty of people over the last 8-10 years who continue to support the classics no matter how good the graphics are on the latest otherwise mediocre and dumbed-down excuse for a premium game are.
2 notable ones that stand out:
Heroes of Might and Magic 3, HD edition. Despite HoMM7 being in development, Ubisoft thought that HoMM3 was legendary enough to deserve a HD remake.
Deus Ex: Revision. More than a HD remake or compatibility update, it looks like they completely changed everything except the storyline and some NPC designs.
Looks like publishers and developers are listening, and there's enough demand that the classics are making a comeback.
