There's little to say on this news post besides the fact that ArenaNet have released a new teaser image of what is expected to be the next revenant Legend. Shiro Tagachi is a famous Guild Wars character and is most likely the revenant's damage orientated Legend. We've no idea how he'll play, although we can likely expect him to use sword(s) as well as daggers. 

Originally a loyal and ambitious guardsman, a descendant of Kaineng Tah, Shiro Tagachi was noticed by Emperor Angsiyan due to his prowess with weapons and thus invited to join the Imperial Guard as the emperor's favored bodyguard. As a bodyguard, he famously defeated an attack by Am Fah rebels in 1368 CC (858 AE), executing all who surrendered and decapitating their leader. In 1375 CC (865 AE), he rescued Angsiyan's son from Celestial Ministry rebels, mercilessly slaughtering them all in front of the boy and later mounting their heads in front of the Ministry. Though not often admitted by the government, Shiro Tagachi was an integral part of the peace treaties Angsiyan was forming with the Kurzicks and Luxons, and was the one who convinced their champions to work together.

I'm hoping that ArenaNet use many of the skills that Shiro had access to in Guild Wars, as I think it'd be an excellent cross-over and most would actually suit the revenant. Take a look at his skills here and as always, I'll keep you posted when I learn more.
