I'm curious as well. I'm able to do everything and more in Vim/MacVim that I was able to do in TextMate 1. Sure, it may not look like a "native" app, but I don't see how that should be an issue. You want to focus on the text, not the pretty box around the text.
Edited to add: Granted, a lot of the niceties have to be installed after the fact as a plugin, and are not built in. Where with Sublime Text 2, perhaps a lot of those things are there from installation.
