Yep, looks like the songs are set up for an Yui OP and Mio ED. Very glad that Kyoani stuck with the same music production staff for all three K-On! installments(Tom-H@ck OPs and Maezawa/Komori EDs).
A bit sad...no pseudo-English OP title. "Ichiban Ippai" just doesn't look as cool as "Cagayake!GIRLS" or "GO! GO! MANIAC" or "Utauyo!!MIRACLE" .
