Searching through the various sub-pages of the Hasbro website keeps giving up more listings of future Transformers, thanks to a TFW member.
Wave 3 Voyagers and Legends for Generations are...
Voyager - Hotspot (with art that uses the Classics Inferno mould, and a mistransformed vehicle mode with the Defensor head showing), Cyclonus (looking very nice from the top).
Legends - Viper, Groove, Warpath.
