I don't know the specifics, but they overreached bigtime with Empire, there was just too much tedious crap to deal with and it left a lot of people feeling burned. I (hope) this means it will be a more scaled down version a la Napoleon.
Leave in the good stuff and discard the fluff.
They don't need to, WoW generates hundreds of millions of dollars each month.
yea i have serious doubts about D3 coming in 2011
Guild Wars 2
BF3
The problem with making a new MMO as opposed to more add-ons is you risk splitting the player base and losing many people in the process.
Guild Wars has clearly been reluctant to do that.
