We have no clue where your getting six years from for GW2. Rrt had been only announced back in 2007 (same time they started it). That they to announce it that early simply because cancelled Guild Wars: Utopia and ArenaNet wouldn't seem like leaving their community out from the loop and feeling like they were deserted. So GW2 only has experienced development now for four many the normal MMO development time is 4-6 years. Considering there're aiming for beta by the end of this year and release from the first 50 % of 2012.
