I'd say that every installer posted for the public by muton or Destructavator or anyone else counts as a 2.3 RC release, meaning that it's as good as you've got until that point unless you compile the code on your own.
It's no use pestering the developers all the while and frankly, it's actually insulting to them to make demands like that.
The more people take part, contributing code (not for me, this one, I'd screw it up), reporting bugs and testing things, the quicker things will happen, but they will all happen in their own good time.
