I don't know, I kinda like her with bangs
She looks younger, cute too, and having something new isn't bad. 
But I still love her without bangs either, she looks good both when she's covering her forehead and when she isn't.
Whether Kishi starts deciding to portray her with bangs or not won't really bother me as I've found myself adoring this new look. STILL, I'd have to say I prefer her showcasing her trademark--ESPECIALLY NOW WE JUST GOT THE SEAL TO BOOST IT.
On top of which, Naruto simply loves her forehead. Wouldn't wanna take that away from him now even though we know he'd love her just the same--long haired, short haired, bangs or not, heck even if she'd turn bald--to Naruto, just like me, she'd always be my Sakura-chan. 
I think the seal may be purple too, but I wouldn't mind if it weren't. I'm kinda curious and excited if it isn't though.
