this is how I think the characters will be announced
Comicon - Alex, Rolento
Loke Test 2 - Hugo, R.Mika
Loke Test 3 - Elena, Charlie
Surprise announcement - Q
All these characters are the ones that were released for PSN as avatars. At Comicon there are 2 empty slots, so one 2 characters announced for Comicon, but there is space for 6 slots, the other characters will be announced in each Loketest. Q, the 7th character will be a secret character who is selectable by pressing down on the random cursor.
