This is it, the realest Devcon that's ever been made!  Back in the early BotCon days, they flirted with at least two potential Devcons -- one from Machine Wars Mirage (which I made a custom of) and one from Energon Slugslinger, and then in Later BotCon days they actually did make one from Generations 2011 Scourge.  I mean, it had a new weird-lookin' duckface but it was made.  And then there was that bizarre Platinum Series Sweep with the retooled Devcon face??? what

But now Hasbro has actually gone and done it and made a regular retail looks-like-the-character-model Devcon!  Legacy Devcon is a heavy partial of Studio Series 86 Blurr, and when I mean "heavy" I mean he only keeps the feet, thighs, and some minor interior joints. Everything else is new.  He even transforms a little differently, in that his arms don't switch positions on the torso anymore, and the only kibble now hanging off his forearms are some tiny wings.  

He comes with three accessories: his arm-mounted blaster and two vehicle mode thrusters.  The instructions show you stowing them on his back in robot mode or plugging into his blaster, but they're perfectly sized to fit inside his leg cavities.  Keep those suckers there.  

The Transformers Generations lines continue their adherence to animation scale, keeping Devcon at Smokescreen height.  He's actually a fraction shorter than Blurr due to the retooling, and that's good.  Being taller than Smokescreen would be *adjusts glasses and pocket protector* less accurate.  I know your brain tells you that Devcon's a bigger guy but your brain is wrong.
