It's also a matter of how much the 3rd party bits negatively impact any other modes or can even be carried in other modes. The DNA Design upgrades for Studio Series Devastator carry awkwardly on the Constructicons when they aren't combined. Though I suppose at least the beds of the two dump trucks weren't much to look at anyway.Well, you can bet that there will be 3p support for any shortcomings (haha!) that it might have. It will just depend on how much more you want to spend on improvements.
But yes, 3rd party upgrades are generally obsessed with increasing the height of figures. So it'll happen. :3 I won't be buying any, though, because I'm cutting back (...somewhat). Heck, maybe I'll pass on Dinoking if the changes from Volcanicus aren't enough for me.
