In order to improve Vocaloid at some point their going to have to make significant changes to the point where it won't be the same engine anymore. Its capabilities will a leap compared to V3. :-/

Hence why I have no doubt V4 will occur. With each significant step in engine version, the vocaloid vocals will also have to take a step too. As it stands just between V2 -> V3 we have the introduction of triphons which put V3's above V2 vocals in terms of quality overall.

Plus, Yamaha has not stated otherwise that they are going to do this to V3. And honesty; it makes them more money to add a extra number each time. :-/
