I've been mulling it over about the new deco for this version of Scourge, and feel that, despite my (and many others') initial misgivings about it, I'm slowly warming up to it on the notion of it not being a new version of Scourge in his original body, but a new version of Scourge in an upgraded body.
There is precedent in how both of his Takara Legends toys have been depicted as new, upgraded bodies for him instead just reinterpretations of his original body:
His Deluxe toy even has red/pink chest windows like this new one does. Granted, in that Deluxe toy's case, it was because those chest windows were also his actual truck windows, but it's still a case of his robot mode having red/pink windows.
But while that gives precedent for the color of his chest windows, it admittedly doesn't do the same for his torso being black instead of gray. Well, there just so happens to be another toy of his that, in fact, does. Scourge's very first upgraded-body toy had a black torso instead of a gray one. And that was Destructicon Scourge:
Sure, that one also had the gray-and-black chest windows and shoulders, but I do feel that it could be the missing link between the original Scourge and this new one.
In fact, one could even call the Velocitron Scourge the missing link between all of the others Scourges. If one wanted to consider the Destructicon the actual second body upgrade, then the Velocitron one could come next, followed by the existing evolution of Scourge's bodies, giving us the following pattern:
Body 1: Gray torso, gray-and-black windows
Then he undergoes a significant body-change in which his torso changes from gray to black (and his overall shape changes), but his robot mode windows stay the same.
Body 2: Black torso, gray-and-black windows
Then he goes back to his original shape, but keeps his black torso, and his robot windows change to red/pink.
Body 3: Black torso, red/pink windows
Then he changes again, his torso goes back to gray, but his windows stay red/pink.
Body 4: Gray torso, red/pink windows
The TFSS version is similar enough to just be considered the "Hasbro version" of this form.
And finally, he upgrades one more time, keeping his gray torso but returing his windows to gray-and-black, restoring his original deco to come full circle.
Body 5: Gray torso, gray-and-black windows
