After playing with TM2 for half an hour or so, I don't think I'll be switching back from Vim. I was hoping for some split-screen action and maybe some advanced autocomplete intergration, but it doesn't seem to have either. It's looking to be a great update and improves on a lot of things in the existing version, but if I were honest, I'd have to say I wouldn't bother upgrading if it wasn't free.
That said, it's obviously an alpha release, so who knows what the future will hold.
