I know Mattel is going to play the hits (as well they should), but if they want to get collectors on board that are fatigued from collecting multiple DC lines over the last 25+ years, I think it would really behove them to include some deep cuts from the jump.
For example, I wouldn’t expect a reasonably complete Legion of Superheroes unless the line is thriving in five to ten years, but if they throw in a Shadow Lass, Phantom Girl, or Dawnstar in the first five waves, at least they’ll have us on the hook with the (implied) promise that more will folllow.
Same thing with the Rogues. Like Reno said, give us a Weather Wizard. That’s something new. If we’re five plus years into this thing, and all we have is Captain Cold and Mirror Master…BFD. We’ve been there and done that…several times. On the other hand, give us Weather Wizard, Heatwave, or the Trickster early, and we’re going to feel pretty confident that if the line is successful, we will eventually have a complete set of Rogues.
I’m not expecting waves full of these characters. That would be commercial suicide. But one or two every few waves would probably be enough to keep people (like me) interested.
