Went ahead and pre-ordered Cloudcover on Walmart. The comments here about their pre-order history has me leery, but they give me free shipping and didn't feel like paying $7 shipping on a $35 on Pulse. So, will take my chances.
It'd be cool to know what some of the thinking/discussions were about all of these cancelled G2 designs. I always wonder if they were intended to come out at roughly the same time as (or instead of) the other G1 mold re-uses, and got thrown out for being too 'out there', or if they were intended for later down the road, and then thrown out when they decided to shift to doing new molds instead. There does seem to be a mix of approaches - some guys are nearly the same as their originals (Optimus, Inferno, silver Dinobots), other guys have similar but subtly different decoes (Jazz, Starscream), some guys have the same deco with one major color shift (Constructions, second wave Dinobots), then there are some guys with wildly different color schemes (Ramjet, Aerialbots, Combaticons).
My thought is that the G1 re-uses were just place holders until the new figures could be made.
