It looks like there's a possibility of the pre-order costumes being put on the PS Store in the future, SB is currently working on character models for Kat and Emmett, and there's a possibility of the soundtrack being released.
There were a few more minor details as well, but those shown above are the meat of Seth Killian's comments.
