Airazor from Slipstream wasn't on it, replaced with Arcee from Legends Blackarachnia, which I thought made sense as there was a previous Botcon Arcee from Transmetal 2 Blackarachnia.
The other thing missing from the rumours list was the Customise Class Ratchet, which I would have considered worthy of a more main line release as part of another Autobot Combiner. The item the list had on it was Blue Bluestreak from Dead End/Streetwise. This made vague sense: there's already a Streetwise use in the Botcon exclusives and the customise class toy tends to be a reuse of one already in the exclusive packages. Although Blue Bluestreak is a "variation" that doesn't exist in the original Transformers line, although it does as a Diaclone toy , there's a lot of interest in it due to that being the way Bluestreak appears on his boxart and in early catalogues. In the last few years there's been a Binaltech Blue Bluestreak, Beast Hunters Legion and the popular Masterpiece MP-18B Blue Bluestreak. Plus the use of a Blue Bluestreak as a convention toy allows a "proper" silver/anime Bluestreak to be done in the main Combiner Wars line or as part of another Autobot Diaclone Combiner boxset.
Alas it was not be and with Ratchet's appearance my dream of owning all 18 Diaclone Autobots in Combiner Wars form took a severe dent.
Or so I thought....
When the final two toys from Transformers Subscription Service 4.0 arrived the incentive toy was revealed as Blue Bluestreak and in a bag labelled Botcon 2016 no less!
Bluestreak is mainly moulded in blue plastic, with black for the wheels, connector to HFG, knees, waist & combiner connector and white for the softer plastic on upper legs, hips & lower arms/elbows. The bonnet is covered in silver paint, a little too far to the edges for my liking but seemingly accurate towards the original. The lightbar is still on the roof and is a little more obvious here than on Smokescreen as it's been picked out in black. The use of the word turbo on the side of the car looks a little odd though and yes, the white upper arm/elbow pieces do rather break up the side of the car.
Robot mode looks superb though, no complaints there.
After getting excited about the possibility of it being at Botcon and then let down, I'm really glad this toy has been brought out by the club and very pleased to own one.
