It should have the Skyrim engine, or even something better. The Gamebryo engine gave some console players a lot of trouble. However, Skyrim's engine ran very smooth on my Ps3, only froze a couple times from extended play. So what do you think guys? Do you think Fallout 4 will ditch the old Gamebryo engine Fallout 3 and New Vegas were put on?

Bethesda said that FONV was the last game to use the Oblivion/FO3/FONV engine. As for future games, they haven't said anything in that regard, but we do have http://www.gamesas.com/topic/1414088-fallout-4-speculation-suggestions-and-ideas-thread-90/ for such discussions.
