I like the RetroDuo, but I'm interested in this if they manage to get the light gun working for the light gun titles across all three platforms (The NES Zapper stuff, SNES Superscope and Lethal Enforcers, and whatever the Genesis had).

Also hoping the Genesis side supports Japanese titles, I want to be able to play Turbo Outrun. I was considering a Gen-X or GN Twin just for that purpose, but if this can do it I'd rather go for this one.

Beyond that, I hope they think hard about button mapping so the controller is as suited as possible for each console.
