i fear that might not be the case if/when it ever comes out. i have a sinking feeling textmate 2 will end up as a mac store only app, and there's no way to provide free licenses to previous owners of non-mac store licenses.
If he is interested in putting it on the App Store, I doubt such an established developer would sweat maintaining a parallel standard version. Although the free upgrade promise is/was rash, I think it's too late to go back on it.
