I have the roadmap page here where I'm trying to list all the cool things I know of that are going on for the devel branch and who is working on them currently.

If I've left something off you might be working on, let me know on this list.
I hope this also gives folks and idea of all that's pouring into 1.8. This looks to be a very exciting release -- lots of big, long running features -- not just small stuff. I am excited.
1.6 was mainly a performance release (though also contained a lot of nice mini-features, and the new s390 PXE simulator), but I think this one will be bigger and better.
