Other "AAA-grade" engines exist that do these things, but most are in-house projects and either never licensed out or are done so with very little public fanfare. There are also a very large number of smaller studios with really amazing internal engines and tools that you'll never hear about (which is too bad; some of them really should license their tech).
A lot of smaller indie teams are working with quite capable engines and in-house tools. I know I've said more than a few times here that I had no respect for indie games, but this last year has really seen a huge turnaround. Especially with the very recent trend with Kickstarter and experienced game devs jumping into the indie scene, there's some cool stuff happening that I never would have expected a year ago. Lots of new blood with a solid fundamental understanding of both game programming and general high-quality software engineering are showing up, many migrating from the big companies after the last few years of the big publishers mistreating their developers and artists. I'm still a bit wary of the indie scene (not sure if it's a bubble waiting to pop or an unstoppable force of the market), but they're definitely doing great things, in part by doing their own rapid-cycle game tools rather than using the big-name clunkers.
