Well, considering the bump in version number, I'd say it's a given. UE -> UE2 -> UE3 were all quite large generational leaps.
If it weren't for the fact that Tim Sweeney is the brains behind this, I likely wouldn't give Mark Rein's (a very good marketeer) words much credit. But Tim Sweeney is a pretty savvy engine designer who always seems to be fairly in touch with the direction hardware is going. A bit of a different approach to Carmack who tends to try to funnel hardware into his vision of future 3D rendering.
As well, having Dx11 presumably as a baseline should make for some potentially fantastic results. In other words designing around Dx11 from the start rather than designing around Dx9 and trying to then add or port it to Dx11.
