on shdowrun they got it as December 24 2011. I have heard others say it was 2012 and just the other day while i was helping the wife pack for her work trip to massacheutes "decoding the past" episode 74 was on and the whole episode was about the date which they put is December 21 2012.
so who is right?
when magic comes back and I become the most powerful magic user I want to prepare so I can start my training right away. Those hot super models won't know what hit them! "you want to give yourself to me". Awesomeness
