The first paid expansion to Guild Wars 2 has just become available for pre-purchase ($50 for standard edition). It includes the full Guild Wars 2 game, as well as access to any remaining Guild Wars 2: Heart of Thorns beta/testing events.
The Ultimate package ($100) isn't a bad deal, since it includes the standard game, an additional character slot ($10 value), in-game miniature toy, in-game special finisher move, special guild hall decoration, special glider (wings) skin and 4000 gems ($50 value).
