If you're on a break from college and/or are a bum that does nothing all day, then sure this is a long wait.
Seriously, it doesn't feel too long ago that Rih was releasing FFS and AO2. I'd suggest doing something with your life instead of refreshing her Twitter feed everyday in hopes of a release. It's not coming until next year. Move on.
Because that's not her job, she's just the singer, and in her contract is not implied that she has to write her material. She can get write credits and still be involucred in the writing process, tho. It's completely normal with every multimedia production to be made by a team and not by a single person.
