Green '68 COPO Camaro recolor
Harley Davidson Fat Boy
Batman The Brave & The Bold Batmobile recolor
Snow Stormer (basically a tracked ATV/snowmobile hybrid)
Ice Shredder (a bobsled, which is awesome)
Loopster (a rollercoaster car that looks to have a third axle in the middle and it appears that multiple Loopsters can be connected together like a real rollercoaster, should prove to be popular)
Those three HW original designs look to be some of the coolest ones to be released in recent years.
