VOCALOID isn't straight auto-tuning, though... there's so much more to it.

The fact that samples have to be edited to include diphones, triphones, proper transistions between phonemes and other fine details required for a vocal library, (on top making sure the sound samples themselves are acceptable enough) is a much more draining and time-consuming process. Plus you also have to consider the arrangements made for recording/re-recording with the voice providers... not all of them are available at the drop of a hat, and from what it's been said before sometimes the recording process can take days to weeks just to get through the scripts.

Of course, it would have to take someone who has directly worked with the development kits to explain it in more detail... these delays are to be expected when dealing with advanced stuff like that.
