Blizzard are giving fans who cannot make one of the seven official launch events in Europe (London being one) the option of staying at home and witnessing the festivities on their computers.
"The Digital Launch Event, scheduled to start at 22:30 Paris time (CEST), will bring all the excitement of the live events from around Europe into your home. Blizzard artists and developers including Greg "Ghostcrawler" Street will be on hand in each city to offer insight into the latest expansion, and the show will also include spectacular entertainment such as a live orchestra playing music from Mists of Pandaria, MANAO - Drums of China and much, much more."
That's how the event is described by Blizzard, and you will be able to check it out on a dedicated mini site or on the Youtube channel.
