Found more info about incomming Guildwars expansion and sequel from PCgamer magazine. It deserves a new thread..
They are thinking to raise the Level cap (finally) could be raised in the sequel to 100 or unlimited!! ,directx10 support , complete new combat system ie.. players will have more control of the character,, jump ,swim .. perhaps oblivion combat style ? and less instances ,they want up to 100 players in the same quest or mission.. perhaps more similar to WOW when it comes to online quest but without the monthly fees .
