Autobot Cheetor - minor redeco - with the vintage reissue, that's three versions of Cheetor at Walmart... and in general for the rest of us. Seems like a wasted slot for a minor redeco.
Autobot Deep Cover - redeco Sideswipe/Deep Cover - another wasted slot, as we have the darker deco out at the same time through different sources (which for many global fans would be through the same online stores they import through).
Decepticon Sparkless Bot - redeco Siege Barricade? - I love the way they coloured the toy to make it look like something dug up from a kids backyard a decade later. It is so distorted visually, I don't immediately see it as being yet another (boring) use of that mould.
Quintesson Deseeus Army Drone - black redeco Siege Ironhide - since the cartoon uses a lot of recycled moulds, this one probably makes sense... but to me it just looks like a black Ironhide. At least give it a new head.

I wonder if there is supposed to be a fifth toy, like the first two waves?
