There's a bit of confusion regarding the nomenclature, since this could be considered Legacy wave four OR Evolutions wave one, depending on whether you count them as separate toy lines:
Breakdown is straddling the fence, technically an Evolutions toy but being released in Legacy packaging so that collectors who keep their toys in the boxes (hee hee snort) can have a consistent look for the packaging.
I'm very excited about Breakdown, and of course they've been teasing Needlenose forever so I'm so glad he's finally on his way. Armada Hot Shot I don't really care about, and Scraphook doesn't interest me.
Zob (is selective, except when I'm not... I'm selectively selective)
