Smokescreen being the Alternators first release was the smartest move of the line. It just had the right level of visual punch to really get people's eyes on them and get everyone interested.
It's what got me. It was just such an amazing looking design coupled with being a return to "my" Transformers characters (I grew up in the heyday of G1. I was aware that the brand had kept going after I stopped watching, but hadn't really paid to much attention to it.) Plus, the design, the super-realistic car mode, the attention to detail, etc. were all so well done that it felt "adult" enough for me to actually buy as a collectible type thing instead of a "kids toy," as I was way too old for that sort of thing (gotten waaaaay past that hangup now.)
Man, I'd love a fresh take on the Alternators designs in the main line. A new GT that locks together better, a non-frustrating Mustang (use it as Wheeljack first, want to see those colors). A pickup truck, maybe sharing engineering with Hoist/Trailbreaker. The Tracks design. Even just use like the Smokescreen rally color scheme on the Datsun mold, and the Dead end colors on the Sunstreaker mold.
Oh, absolutely. I really wish Hasbro would do more references to Alternators. Give us a Selects Smokescreen in his Alternators colors, or redeco a Windcharger as Decepticharge, dangit!
