CHECK THE LOWER RIGHT arrow link for a video of Elisabeth and Mature in action near the end of the new trailer
The new console website details modes, online play, and other things.
This is definitely not all, many expect K’ and Mai to be revealed at E3, since various sources point out that there are over 22 characters, and rumors of 6 planned for the console version. And the mentioning of hidden characters (therefore, Mature and Elisabeth don’t count as hidden characters since they have their own box in the select screen).
but some say the number 6 is referring to amount of players in online lobbies,
so chances are, if K’ and Mai are not on the disk, they might be added through DLC.
The artwork hints seem to strongly suggest they are the hidden characters, though. so there is a good chance there will be 4 added characters instead of 2.
The one thing the new trailer displays that the online section doesn’t mention are the Clan online features, which is still unknown how it works, but clearly displayed in the main menus of the video.
