We speculated about it, Bethesda leaked it in tandem with Walmart Canada and now Jade Raymond offered some insider insight - the next Splinter Cell game exists, at least as a concept, that was developed during her time at Ubisoft.
Jade Raymond has confirmed that she and her team started working on a new Splinter Cell at some point during her stay at Ubisoft. Apparently, the team created a design for the next instalment in Splinter Cell series but it never saw the light of day. Raymond left the company in 2014, so it is possible someone else picked up the project by now.
Information coming from Ubisoft earlier this year revealed they were working on four AAA titles, with two being unannounced at that time and we that Sam Fisher could see some more action, alongside The Division 2 or Watch Dogs 3. Only The Division 2 was confirmed at a later point in 2018, but that removed neither Watchdogs 3 nor the next Splinter Cell from the possibility list in FY 2020.
Another leak in 2018 hinted at the next Splinter Cell. Since it's not Australian rating boards, it had to be Walmart Canada, so the latter Rage 2, Gears of War 5, Just Cause 4, Forza Horizon 5 and a new Splinter Cell title. All of these were later officially confirmed and announced, except Splinter Cell.
Ubisoft gave strong hints there is a new game from this particular franchise coming at some points, as Yves Guillemot kept the fans over social media and forums. To top it off, the company created a crossover event for Ghost Recon: Wildlands, where Sam Fisher appeared and came to a startling realisation, seen on the picture below.
With the rumour mill in full swing, Ubisoft are surely gaining hype for the potential new singleplayer game. The only wrench in their gears is probably the matter of microtransactions as it would be hard to implement them in a Splinter Cell game, since the series is neither RPG nor multiplayer focused.
