I depends on what you consider a "current version." What @ALC said is correct. "Major" version (V2 to V3, V3 to V4) etc are not included. However, the rest of the synths can be upgraded to the latest minor version of what is included in that specific version of V Collection.
I'm a big V Collection (and Aruria in general) fan. I normally wait on versions of the V Collection until they drop to $99, so I've been through this a few times.
