Not excited, but interested.
I don't pay a lot of attention, but when I do, I'm in awe of the speed of development these days, and even more in awe at the manner in which the development takes place. I don't work in an environment where we receive patches from strangers, or even people we've not met. But I understand that the Linux kernel and many other big projects included in most distros constantly receive development enhancements and bug fixes from all over the world. They're systematically thrown into a build, tested and judged for acceptance. Gosh that's a big effort!
