I'll address the actual topic first:
Oh, Capcom saying that with fan support, something could happen. Megaman Legends 3 anybody? Yeah, this isn't happening. Capcom abuses their fans like no other company.
As for the older RE games in general: yes, the controls were shit, but they were manageable. The games were fine. Not perfect by any means, and certainly in need of better controls, but perfectly playable. As far as why the newer games won't resemble the older games? The older games took thinking. At their core, they were puzzle games with survival horror elements mixed in to define the series. There isn't a large market for games that play that way anymore. As I've said before when it comes to things this forum would play: yes, we would play it, but we overall, make up a small minority of gamers with generally differing interests from the majority. We'd play another puzzle based RE game, but most people wouldn't. We may not like the new direction RE is going in, but many other people within the majority do. Capcom is working with the shifting interests of the video game market, and we just have to accept it.
