Technically, Vocaloid was 6 years in development if you include Elvis Project as part of it, and in addition CeVIO had a similar amount of time. The V1 engine is regarded as Vocaloids "Prototype" engine and CeVIO was on sale before it was a full working version.

IT actually goes for a lot of things that they can be in development 4 or so years at least before they are released.
