PC Gamer magazine's May issue says that AreaNet will be releasing a Guild Wars expansion later this year called Eye of the North, which introduces a variety of new races, many of which will be playable in Guild Wars 2!
Yup, Guild Wars 2. I heard it will have a Z-axis, which means you can jump, swim, and climb trees/cliffs; it has a higher level cap and even MORE skills; still no fee ; five races (Human, Charr, Norn, Asura, and Sylvari), and more PvP styles and options (added to the original Guild Wars' several ones already). So yeah, it'd be the most awesome thing ever.
