Ri is right. We know PBs are bikini-centric. She had bikini shots on her frst one, it's obvious that she's going to get more bikini shots in this one, and well, it's part of the Love Hello! series, you can expect shitloads of bikini shots.
As for the PB itself...i don't think i'm excited, i'm not even a Koharu fan in any way lol
