Let's not jump to conclusions on the next volume cover just yet , we've still got this week's chapter and next weeks chapter to go through. The focus of volume normally ends at chapter 8. However it hasn't stopped yet. That means either this week's chapter or end of next week's chapter the focus will be complete.
As far as Sakura role only shown in 1 chapter. Look at the situation since 662. Sakura's the reason why Naruto is still alive, if she wasn't pumping his heart he'd be dead. Think about her role was set up for this since then.
Sakura's got a purpose to be in the background this time. So your statement about not having a focus in the volume is completely negated. Had Minato teleported Naruto and Sakura to another location and transferred yin Kurama then I can understand. But that hasn't happened yet.
Look at it this way:
662: Sakura attempts to save Naruto.
663: Sakura tries to keep Naruto alive.
664: Sakura tries to keep Naruto alive.
665: Sakura tries to keep Naruto alive.
How the hell does that reduce Sakura's role/focus to one chapter. Go back and reread the chapters she's been in every chapter post 661.
Edit: oh and by the way when the hell did Gaara tell Sakura to cut Naruto and pump and his heart. He didn't order her then, she did that herself.
