The next game in Tom Clancy's Splinter Cell series, has been called Splinter Cell 6, Splinter Cell: Retribution, and now rumours call it Splinter Cell: Blacklist. A NeoGAF user claims to have seen the game and claims to have proof of the information.
Naturally, there is no official word from Ubisoft just days removed from their pre-E3 press conference. But all evidence points to the next Splinter Cell making an appearance there (or perhaps even more likely at the Microsoft presser earlier that day).
