It seems that the “big announcement” concerning Tsubasa is the release of new CD(s) Drama(s). My thoughts are: If Ohkawa is not writting it/them, I’m not interested xD Yeah, I’m that radical.
It might not be the -only- big announcement. So far all I know is that on edition 20 of SM the readers will be able to apply for a CD Drama, since all 3 have already been released, I’m assuming this is brand new.

Also, the official site for the anime has been updated with the titles for episodes 1 and 2 of season 2:

1 – Dangerous Race.
2 – Three Badges.

So yes, pretty obvious now that the second season will indeed start at Piffle, but let me clear that this DOESN’T MEAN we won’t be seeing Sharano/Shurano arc later, okay? Chill you guys, it’s probably just a change of plans.
