With the Zygarde formes being known in their anime-form for quite a while now, it's kind of overdue already anyway...but Masuda has been recording an episode of the weekly japanese pokemon tv show, that is supposed to air on 15th of November. twitter.com/Junichi_Masuda
These sunday-shows sometimes used to be the place where new stuff got revealed (often coinciding with the monthly corocoro that usually leaks a handful of days early), but ever since the announcement of gen-6, we've seen the trend towards them making big reveals globally in a polished manner (youtube, fb, official page), with corocoro and the show tagging behind (probably to avoid speculation about whether leaks are fake etc.).
So I'm confident that corocoro-leaks before the show (10-14th) will include what Masuda will be showing on the show, but furthermore that we will likely even know another week earlier than that.
Any final bets on the titles?
I'm still saying that it's going to be two XY sequel-games. But I've given up on X2&Y2 and XZ&YZ as likely possibilities.... I'll stick with Pokemon XY & Pokemon Z (fits with the upcoming anime season subtitle which is called XY&Z)
