Well, if you just moved all those to the off-topic forum, I'd be happy too, but that just seems like more work for you guys with such a horde beating down your doors.
To me this is more of cleaning out riverside than making a forum of value frankly. Kinda like how some places have a flaming and rants forum.

I guess that is not what you want though.
I just think you guys will need to do something if you don't want Riverside to turn into a GW2 speculation forum, choking out any and all other topics in the frenzy. It's only going to get worse when online game sites start picking up their own previews too. There's plenty of fansites that come into existence 2 or even 3 years before a game comes out and are rabid with fan posts, so don't think it's too soon for everyone else!
