In development since 2011, Frostbite 3 is an improvement of Frostbite 2 and will debut with Battlefield 4 in 2013. It only supports DirectX 11 on PCs. It also features in-game destruction with Destruction 4.0 which upgraded from Destruction 3.0, and it features an entirely new tessellation technology. Frostbite 3 is described by DICE as an upgraded version of its existing Frostbite 2 engine, designed to create a "dynamic, human and believable experience" and allow for improved animations, destruction and AI.
Frostbite 3 is designed to take modding out of our hands, even more than its previous versions. No mods means total dependance on the developers for new content. DICE, don't forget that it was a mod, Desert Combat, that drew the attention of gamers to your team. Now you have betrayed us. Shame on you.
