Some Hasbro proto pics from a forum called Coreplanets.com below.
The toys apparently employ state of the art technology... from 1975.
Looks like they're looking for more "play patterns" for the ship designs... anyone remember the Galoob podracing debacle?
These appear to be about 10 cm/ 4 inches long... right in the Titanium ballpark.
I'm not exactly impressed, to say the least... but there they are.
