A trailer revealing the Thief class in Guild Wars II appeared briefly on the 'net today before disappearing like a thief in the night, but Eurogamer has word that ArenaNet unveiled this new class during their Guild Wars II presentation at GDC. They have word that this character has many of the characteristics you would expect including being especially dangerous when catching opponents off-guard, possessing the ability to hide in the shadows, and, you know, steal stuff. They say he can also dual-wield daggers, swords and pistols.
