Just saw this on the front page, seems like it's legit, as of right now (22nd December 2010) it has 1,117,082 votes which seems like a very big number considering that this voting scheme was opened only a few days ago.
If it does end up coming back there will probably be some people returning to this game!
I say hell yes! It's about time they bring back the old RuneScape and get rid of babyscape. I can't even play because I'm to pumped to just finally be able to go shred up the wild once again and merchant like I use to. Going to be fun.
