The tweet that they mentioned~ I know that sometimes they tend to repeat tweets that have old news just to let people know that things are still going on~
Tales of Festival is this week so I guess they are expecting some news at the end of the week!

I'm gonna guess that there will be a message recorded by Ayu or something, haha. That usually happens with this sort of thing anyway. It's kinda strange how we've had to wait so long for even the title.
