An Amazon France listing adds further weight to the likelihood of Splinter Cell: Blacklist coming to the Wii U. While the page itself is somewhat speculative - the game is titled 'Splinter Cell 6' - the blurb matches up with the retailer'slistings for other platforms.
The outwardly blacklisted Wii U version was spotted on two Ubisoft employees' LinkedIn profiles earlier this year. While the purported Wii U version strains to stay stealthy, Ubisoft is definitely bringing Splinter Cell: Blacklist to PS3, Xbox 360, and PC on August 20.
