顺便贴一个关于 UE4 的说法，继续瞄准下一代多核高清机。

Tim Sweeney: The Unreal engine is really tied to a console cycle. We will continue to improve Unreal Engine 3 and add significant new features through the end of this console cycle. So, it is normal to expect that we will add new stuff in 2011 and 2012. We’re shipping Gears of War now; we’re just showing the next bunch of major tech upgrades such as soft-body physics, destructible environments and crowds. There is a long life ahead for Unreal Engine 3. Version 4 will exclusively target the next console generation, Microsoft’s successor for the Xbox 360, Sony’s successor for the Playstation 3 - and if Nintendo ships a machine with similar hardware specs, then that also. PCs will follow after that.
