Guild Wars 2 is the sequel to the Guild Wars series which is currently in development by ArenaNet. The game will feature a new game engine, changes to character development and the PvP system. Guild Wars 2 is expected to go into beta test in the second half of 2008. No release date has been announced.
There will be no monthly fee associated with Guild Wars 2 to keep up the tradition of Guild Wars. Mike O’Brien has stated that expansions or mini-expansions are more likely than standalone campaigns, but a final decision hasn’t been made yet.
Guild Wars 2 will be written to run on computers with moderate specifications, but will have higher requirements than Guild Wars.
The original Guild Wars will continue to be supported after release of Guild Wars 2. This will include continued holiday events and tournaments.
