Yeah, I looked into this. Not gonna bite.
From the history of a series with easily over 100 possible characters, we get confirmed versions of three characters from the first season, one character from a season that is only memorable because of how badly they screwed it up, and a quasi-original character from the comic books (which, admittedly, would be neat *if* it was in addition to the other 100+ possibilities).
The website shows 11 other slots (one of which would seemingly go towards the third Season One character confirmed but not shown on this page)... leading me to think this will either be a half-assed effort *or* a DLC money pit for a hundred quickly chopped together skins.
Plus, the fact it's digital only... Pass. Just pass.
