Can anyone give me a rough idea of size, as it's been a while since I bought a Transformers toy

Rhinox is a Voyager and Waspinator is a Deluxe. Deluxes I'm familiar with - unless they've changed since the original BW days. But what is a Voyager? Are they akin to a Mega or Ultra from the old days?

And what sort of price are we looking at for these respective size classes?
