Yeah, Herb. I kind of feel the same way. I kind of dislike the whole cash-grab-ish feel of the survival horror genre as a whole, because it has let me down a lot over the years, and guys like Nemesis as well.
Personally, I would have rather seen a third Revelations game being announced instead, but I've been after a fully fledged co-op game for years. I sincerely hope this is that game for a lot of fans, and it's not just another milking tactic. It's definitely something fans have been asking for, so I hope it's a "ask and you shall receive" kind of thing they have going.
But you're right about them always revisiting Raccoon City. Capcom has a love boner for the year 1998. After this game and the remake of 3: Nemesis, I say it's definitely time to put a halt to all of that backtracking, and really push on ahead. There's other locations (and years) they could be exploring now.
