Probably because if he posts that he submitted the update, the server would crash from all the Facebookian hype.
Not everybody actually believes that the update was sent, though, that's the problem. Anyhow, it should only take around 5 minutes at most to announce on his Facebook and Twitter that the update has been submitted, he could have done it yesterday...
he already said, probably wont tell face book because of this (**** RobTop, **** Apple, ect ect) that's probably why, or what if hes setting up the other pieces of the changelog?
Well, he's definitely the real RobTop ( I checked his profile, it was the same on Etzer's stream, who was proven to be real by RobTop himself)... I can't say why he's taking such a long time to announce such a big update. Well, RobTop himself said the Facebook comments don't "faze" him, so he probably assumes that everyone already knows...
I'm pretty sure he doesn't want **** RobTop, so in order to do that he needs to announce he submitted it. Then **** Apple will arise until 2.0 is actually released, so it's either RobTop or Apple. And I bet I know what RobTop would choose.
