And since they always announce famous Disney characters during the Comic Con, the chances that Mekia = Tiana are getting stronger ^^ I'd say it's a pretty safe bet. If we find out that Adelaide and/or Rose are also coming, the chances will be slimmer (since they're bringing multiple guest stars) but as long as it's just Mekia...

From what it seems, unless a surprise, Adam gave the whole list of who would be present.
