It seems that Ubisoft registered a new domain for another CSI game, the title being CSI: Hidden Crimes:

While the previous games have been mostly panned by critics, they're definitely profitable--which is why it's not surprising that Ubisoft is developing another title for the franchise. Interestingly enough, most of the games have been developed by Telltale Games, the creators of The Walking Dead and The Wolf Among Us.

The last games to be released in the series were CSI: Fatal Conspiracy and CSI: Unsolved, both out in 2010.
