The next-gen update includes native applications for the consoles, Performance mode and Quality mode settings, as well as stability improvements and fixes. This means the game will be playable up to 60 frames per second and with an increased resolution.
Really stretching the definition of "next-gen" there. I'm pretty sure those have been standard for years now. But then it is Bethesda we're talking about, still using the same hacked-up engine from Morrowind.
