PowerFX confirmed V4 means "Vocaloid 4" in regards to at least the engine.

So regardless the 4th version of the engine is due.

However, the one thing we do have to watch out for like with Luka V3, is a change of name, who says it will be called "vocaloid4?". We're presuming based on Vocaloid, Vocaloid2 and Vocaloid3.
