CFM has always worked on both projects, its just the focus is on the Luka product. Just because a developer goes silent doesn't mean there is no progress being done to them. Projects take sometimes a couple of years to finalize. The Kagamines are confirmed to be coming after Luka, so attention will turn soon on them now Luka is released.

CV04 was confirmed when all other updates are done and dusted, sadly engine versions come out before they can ever finish. If you don't want to be kept in the dark on CV04, then there are still other studios. CFM is always caught in the popularity of their current vocaloids, especially Miku who is a big money spinner.

Developers rarely give day-to-day talks on their Vocaloids and you should be not alarmed when one goes silent.

Also not everything with ruby has been so serious... If you read the dictionary stuff there is a lot of joking around involved.
