At one time, Splinter Cell was arguably Ubisoft’s premier brand, with new entries coming out every year or two. That’s no longer the case, as it’s coming up on six years since the release of Splinter Cell: Blacklist in 2013. Will Splinter Cell ever return? What, exactly, is the holdup? Ubisoft CEO Yves Guillemot explained the situation during an IGN Unfiltered interview, saying they didn’t want to revive the franchise unless they could do something unique with it…

“When you create a [new entry in a series] you have to make sure you will come with something that will be different enough from what you did before. Last time we did a Splinter Cell, we had lots of pressure from all the fans saying, ‘Don’t change it, don’t do this, don’t do that.’ So, some of the teams were more anxious to work on the brand.
