UPDATE: A Warner Bros. representative has confirmed that "Monolith is not developing the PS3/360 SKUs. Behaviour is our partner focused on developing the PS3/360 and they are giving those SKUs their full attention."
ORIGINAL REPORT: The Xbox 360 and PlayStation 3 versions of Middle-earth: Shadow of Mordor are being developed by Naughty Bear studio Behaviour Interactive, according to the latest issue of Game Informer.
Only the PS4, Xbox One and PC versions are being developed by Monolith, the mag says.
Besides Naughty Bear, Behaviour previously created third-person shooter WET, Doritos Crash Course and Rango: The Video Game, and developed the PSP port of Dante's Inferno.
VideoGamer.com has contacted Warner Bros. to verify Game Informer's claims.
Monolith warned fans to expect fairly substantial differences between the last and current-gen versions following the game's reveal earlier this year, with neither the 360 and PS3 versions expected to make full use of the game's Nemesis System.
Middle-earth: Shadow of Mordor releases on Xbox One, PS4, Xbox 360, PS3 and PC on October 7.
