Since this was being touted as a Gen1 themed set/year, I'm expecting to see characters like Treadshot be homaging their Gen1 versions, not reflecting any following versions that were a completely new character with the same name (because of Hasbro name recycling).

As for the Soundwave bandanna - I'm not sure why they are charging extra for it, but they had a good reason why it wasn't included with the toy (because it was cheaper to produce in America, than trying to get it done in China and then packaged in with the toys). If they went to so much trouble to create it for that toy, they should at least be giving them away with the box-sets... unless they only made a small number, and will sell out real fast.
