According to a rumor posted on the SarcasticGamer website, the voice of Sam Fisher will not be making his return in latest Splinter Cell installment. Sam Fisher was voiced by Michael Ironside, and it seems that an internal dispute is paving the way for a new voice talent in coming Splinter Cell games. According to inside sources at Ubisoft, Ironside and Ubisoft have been at odds for some time:

"He was getting to way too egotistical about the project and extremely difficult to work with. He was also asking for a sh*t load of money… He pretty much tied his own noose."

No official reply from Ubisoft on this matter, but that’s probably because Conviction remains very much up in the air.
