Well...while I wouldn't normally say Beauty Pop makes me unhappy...I agree with you here, I wish it were longer! D: Hopefully Viz will license Kiyoko Arai's newest work, Yomogi Mochi Yaketa?! Or really any of her other works...she has quite a few under her belt already.
Otomen is still running in Japan (at volume 7 already), and volume 2 comes out in English in May. : D
Skip Beat is only so slow because it's basically caught up with the Japanese volumes (still has a few to catch up, but it's really close).
