From my understanding the terrordome construction dio with the yellow hiss was not a hasbro dio but an entry to the dio contest. So I don't think we will see anything from that dio. (yes that's the hisstank that beat me in the custom tank contest @ hisstank.com, but I don't hold a grudge
)But back to topic, I still don't know what to think about the new hiss designs. The little scout hiss or whatever its called looks small and like you said, would be best utilized as a "bat on wheels" but I love the old hiss and I'm still not sure I could love the new one
on a side note: Considering cobra is a terrorist organization, with at least some point, a financial agenda. Wouldn't it make more since to just buy a used bulldozer? You know instead of redesigning your tanks and repainting them. I mean, you own the island, the is no attack coming per say, and the yellow vehicles don't have weapons, so buying some construction equipment has got to cheaper and better for the bottom line. But he beat me in the contest, I don't hold a grudge, I'm just saying.
