GameSpy.com has posted a new interview with Epic's Tim Sweeney, talking to him about the features and benefits of their Unreal engine. The interview reads like a promotional brochure for the Unreal engine at times, but Tim does talk a little about some of their upcoming features. Here's an excerpt:

We'll shortly be releasing our new skeletal animation system for licensees and the Unreal community; shortly after that, a supercool terrain system--already up and running--that moves the Unreal engine into the realm of large, detailed outdoor environments; and support for Windows, PlayStation2, Linux, and (when the time comes) X-Box.

There will be a lot more after that. We've always stayed on top of the latest technology and hardware support, and are in the early stages of radically cooler new features. But we're also trying to be up-front here, promoting and promising what we have up and running well today, rather than the far-off speculative stuff.
