One day, everyone will learn the meaninglessness of release dates and ignore them all together.
A release date is relevant within a couple of weeks of release. I'm not terribly involved with MT, but in the capacity that I am indicates that MT is not within a couple of weeks of release and that it will take quite a bit more time to complete.
The best ETA that I, Styxx, or anyone else on the MT team could give you would be between now and before the sun explodes in several billion years.
Now when its the other way around an I'm the fan and the other person is the developer, asking for a release date usually means how are you guys doing on the project. Again, I think its going well but I'll let Styxx say as little or as much as he wants.
Be paitent and wait to see what these guys can deliver
They will tell you when they know.
