^ You mean judging by the screen time they had in the PV? (Thinking to myself...) They wouldn't do a mass graduation, surely? Idoling!!! would lose their spark if they graduate any of the remaining 1st gens imo! (>_<)
Lovin all that screen time Ruri is getting just in this little preview ver. It kinda makes up for the lack of it in Sakura Sankyu-!
but even so the 1st gen is still featured a lot longer than Ojima
