We all want a release date. I take a little consolation in the fact that it means we might be getting even more content on console. I hope it means the game is still in development.
I would love if Tekken could get an in-game version of a character and story encyclopedia. If would be great if it was interactive and was read by the voice actors of the respective characters that talk. King, Armor King, Panda/Kuma , Roger/Alez and Dragonov could be the exceptions because they don't talk much. Like I've said before it would be nice if it could cover their story/lore contributions in each game.
Something similar to Street Fighter's World Warrior Encyclopedia but better.These voice entries could be nice to earn through gameplay too.
Edit: A very cool way to do this is would be Lei Wulong's interrogation room. The characters talk about their history in each tournament as they get grilled by Lei Wulong.
