There's a big Energon Barricade vibe coming from Sideload; even the combiner head resembles Energon Bruticus'. The combiner parts does a bit of cheating: so far it doesn't look like the parts can be attached anywhere on the alt-modes; and the combiner head is on an entirely separate piece - much like the Transformers Go! kabuto 'helms'. The parts that comes with Shinebug also makes a $25 price difference from the other 4 limb figures. However, the finished combined mode looks super sturdy (check out the shoulder articulation), and each combiner member are arguably left with their first two modes without being hindered by the combiner gimmick (for those that simply just want their CHUG Throttlebots).
Chimungmung has listed Expressway with an ETA for next month, whilst the other two are due for April 2015.
Edit: Went through ToyWorld's website and noticed an Ultra Magnus-like silhouette. Here's hoping for an IDW iteration to go alongside Orion?
