It probably got made private because someone noticed the picture. (I saw Lightning in it as well)
Seems like it.. I hope this is the roster after DLC that would be amazing!
It's fan-art. Someone posted the link to it.
Well there's got to be a reason for why they showed it right? They could have just showed the picture of the original roster.
They were either trolling, or some intern did a google search and didn't actually look at the picture before throwing it up there. You can clearly see that everyone except for the fake characters has a shadow. If this was meant as a "guess whose joining the party?" reveal, they would have put actual work into, not just ripping a pic of the Internet.
