First, I want to let this very clear, Sublime is the best editor I've ever used.
Let me emphasize that it is a really great EDITOR; it has key features that make editing agile, quick, pleasant and awesome.
I hope that other less edit-oriented features does not become the focus in Sublime 2, otherwise it will be as cluttered as any other ordinary IDE.
I've been using Sublime on Windows for a few months now, and I really loved it. Recently I became a Mac user and to hear about Sublime 2 being developed for Mac made me happy again.
But I found some pretty annoying issues; tabs are ugly, interface is messed (see minimap), sidebar is pointless, multi-caret navigation uses bad mod keys (shift+control) and status bar is no more.
I would suggest Espresso interface, which I think is really great, but dressed with usual dark theme. Also, new icon/logo for Mac would be nice.
That's all, I hope I didn't sound ungrateful or surly. I really appreciate Sublime's dev team's work.
