Ubisoft never made any official announcement or any hint regarding the next "Splinter Cell" game since "Splinter Cell Blacklist," but sources say that the next "Splinter Cell" may already be in development and Michael Ironside will return as Sam Fisher once again.

According to a rumor that originated from NeoGAF, the new "Splinter Cell" may be in development right now. A user named Yves Guillemot, an employee from Vivendi, claimed that Michael Ironside will be Sam Fisher's voice once more.

Here's the exact statement that the original poster got from her source:

"Regarding other games, I haven't been involved with Steep or Wildlands, but I was surprised Splinter Cell didn't appear at E3. I know Ironside is back. He was in the studio, I said Hi to him and his daughter. He was shooting a movie with Amy Jo Johnson, and I know someone who worked on that set and Ironside confirmed to him he was doing the new Splinter Cell. I know Toronto has the mocap studio for it.I'm hoping to hear or see something unofficial, if not official, this year, but its been hard to get anything beyond "It's Happening"."

There has been a recent update to the source's statement suggesting that the development may actually be in progress now, according to Ironside himself:

"I have two sources who worked on the set of The Space Between (https://www.imdb.com/title/tt4682922/), which was shooting in TO. Ironside mentioned he was working on a new Splinter Cell. One source is someone I trust, the other is an acquaintance by degrees."

"Splinter Cell's" absences in the last E3 could be a sign, however, that the game is still in its very early stages of development that still warrants further work. Hopefully, fans can get more information about it in the upcoming Gamescom event. Ubisoft will be at Hall 6.1 B020.

Stay tuned for updates about the upcoming "Splinter Cell" game.
