What date and hour Hearthstone Street of Gadgetzan is released?

Guys, do you know when Hearthstone Streets of Gadgetzan expansion is released in Europe, I mean the exact date and hour. It suppose to be on December 1st, but I don’t believe that it will be at 12:00PM, right?

Some guys told me that today past midnight GMT time, maybe even on 1am. Not 100% sure, if I find an official answer I’ll post i there.

I’ve decided to go to sleep and play the next day. Didn’t even get a single legendary :frowning:
