Keep in mind, and I'm the last guy to say Hasbro didn't **** up usually either, but just remember that these were pretty hastilly slapped together (the wave that is) to cover their tracks on the bumping of the Force Unleashed wave, which is now part of 2008's line-up.
I can sorta cut them some slack there, but I mean they have to have had a GI Joe weapon somewhere they could've used too I'd think, but with moving things around at factories and where you have production set for these and all... I can sort of just cut a little slack to them I guess, with the thought that these were really a rush-job of a wave to fill in a slot.
Personally, other than the Clone, I could've done without the wave entirely, and just seen them reship the harder to find figures in this wave's distribution slot instead. Lots of McFigures would've been appreciated at that time I think.
