I'd like to see Hasbro work with Discovery (since the Hub is part of the Discovery Network), to make a line of nature toys.
Starting with Walking with Dinosaurs action figures.

WwD would highly detailed, and usefully articulated dinosaurs that are produced relatively in scale, and to the latest scientific theories.

There would be two scales, Macro and Micro. One for large dinosaurs, and one for small dinosaurs. (because it would be impractical to make a 100'+ sauropod to "GI Joe scale")
The macro scale would produce the large dinosaurs in an affordable pricerange, and keep the animals relatively in scale. There would also be small dinosaurs, such as Velociraptors in the form of miniatures.
The Micro scale, would focus on small dinosaurs, presenting them in the same size classes as the macro scale. Likewise, all Micro scaled dinosaurs would be in scale with one another.

I think another strong property would be Mythbusters.
Geared more to younger kids, the Mythbusters toys would replicate some of their more memorable builds, and create new ones, in ways that teaches physics to kids.
Wouldn't hurt to throw in some GI Joe styled action figures of the five mythbusters (Plus Buster), too!
