I think the Tomahawk/Eaglehawk will be like the SkyStriker: an all-new mould, but with the same basic dimensions as the original. From looking at pics, it looks like the cargo compartment is a little larger. The folding rotors will be great for displaying it landed on a Flagg. And I LOVE the headphones included for passengers, but I bet in 20 years they'll be the next Lift Ticket mike!
I too am curious how figs will stay in the jumpseats without a peg to help hold them. Love the way the seats and the guns look though.
In a Q&A JoeCanuck did with Hasbro, I asked them about how they made the SkyStriker look just like the original but with an obviously new mould. In one of the most detailed answers they've ever given, they stated that they now have a technology that lets them scan an old vehicle and come up with a new design & new moulds. I think the Tomahawk/Eaglehawk is the second use of this technology. This excites me, because it means that even if Hasbro doesn't have the moulds, they can make us a new & improved version of an old vehicle. Mauler or WHALE, anyone?
