Details can be found there. It starts at 2 PM PDT.
I'll be there for sure.
They will be giving out free codes for different stuff on Blacklight: Retribution, though the promo codes only work through the Arc Client of BLR.
They have a special guest, Domino, who was the one who organized tournaments and kept BLR alive back in the day. This just shows that the game is going to be Updated really soon! So, make a move when you can on BLR.
