Thread: Why do the remakes take so long?

It's wrong to call them remades, they are just upscaled versions of the games we play. Really why does it take that long to release a collection? For example: MGS collection was announced months ago before it's release, and there is nothing new content in it (actually they removed some of it, but this isn't about it). There is no difference between the games, only the resolution, and AFAIK, porting a game doesn't take that much time after you get the copyright. So why does it take that long?

Blame it almost exclusively on the marketing dept.
