Looks very promising, makes love with keyboard, supports Python plugins. On OSX it uses different from native controls but I can live with that. Selection with going to line of file e.x. app.js:22 or to symbol app.js#symbol is also very handy. Maybe that will be "Textmate 2" :)
It is not final version, just another alpha release. For now, the change log can be viewed here: http://www.sublimetext.com/2
