Season 1 starts in North America tonight (Friday, Aug. 29th) at 6:00pm PST.
Create a new character and treat yourself to a little carpal tunnel action. Hunter and I will be. The new goodies in 2.1 are pretty fun. I'm especially fond of the greater rifts; I would describe them as: all the adrenalin of hardcore mode, without the loss of your entire character if you fail at the end.
You can chase a treasure goblin through their portal. LOOT ALL THE THINGS.
