The Gen 3 Prius Liftback was new for model year 2010 and the new Gen 4 Prius Liftback is coming out for model year 2016 and looks unattractive enough that I am now considering the Prius V for the first time. The Prius V came out in model year 2011, is the next gen Prius V coming out in model year 2017?
Prius v started with model year 2012. The current 2015 version has the new front end, modified in haste to pass the impact safety test. I can't imagine much change yet, it would seem pretty difficult to design a new v on the basis of the assumed Gen IV photos. Toyota seems to have a lot of engineers that really, really hate cars, but love engineering.
I agree with the comments that you should consider the c and v as Gen 3.5 They even come with colour HSI's
