Known about this event for a bit, but haven't posted any info yet. April 28-29 is the Nico Nico Chou Kaigi (Nico Nico Super Conference). Within that event is Chou Tougeki (Super Tougeki), a special qualifier for Tougeki 2012. The winners for their respective games earn a spot in the finals bracket for Tougeki 2012, totally skipping the qualifier rounds. The interesting thing is that the AE qualifier will not only be singles (winner gets to pick two teammates), but is also double-elimination.
There are will be a concept match event for AE, featuring 8 star players. Five have been announced so far: Haitani, Fuudo, MDR, Mago and Tokido.
