It's clear as rain that they are KO - Look at Hotspot's colors and stickers as well as the too bright green of the Constructicons. Silverbolt is way too bright and you can tell that the plastic is of low quality as its too gloss instead of flat, his gold is also way too shiny and again the stickers give it away.
I will try to get this letter done for you today but if I can't I'll have it done by tomorrow sometime.
BTW: I think the copyright info on these toys also says Hasbro so may not be a good idea to do that.
