Most of those we already knew would be getting some coverage at the show next week, but two of those titles are new to our ears: Star Wars 1313, and Castlevania: Lords of Shadow 2.
Star Wars 1313 is a trademark that's been bouncing around at LucasFilm for a while, but there's been no official word on just what it might be yet. In the Expanded Universe, Boba Fett once used the alias "CT-1313," so the best guess is that it's a new franchise based around Fett's story in some way. StarWars1313.com has also been registered by LucasArts, and currently redirects to the main Star Wars site.
And Castlevania: Lords of Shadow 2 is clearly a sequel to the 2010 title that's hardly a big surprise to finally hear about. But it's not any less exciting to see these two big names revealed by GTTV's mistake. We'll obviously find out more about both of these when the official announcements are made.
Update: Star Wars 1313 now has a Facebook page, also apparently leaked before an "announcement." There's a shot and a description on there, both of which we've reprinted after the break. 1313 refers to "Level 1313," a criminal underground on Coruscant (if indeed this page is real), but there is mention of a certain "bounty hunter," so Boba's not out yet.
Update: LucasArts' official site has the shot, logo, and a link to the Facebook page. It's official, this is the new Star Wars game.
