I don't think it's been approved yet, that's the first thing.

Also, if it does get approved by tomorrow, it might be towards Thursday/Friday. STS doesn't want to release big updates towards the end of the week because :

It doesn't give them enough time to work on problems if they occur (work ends Friday, they can't release on Friday and have problems all throughout the weekend).

The same thing happened when 1.7 was released, it was ready on a Friday but they waited til the next Monday to release it. That way, all the problems that came up was dealt with right away.

Trust me, I'm sure they're as excited as we are to release the update
