Yep, this one is a new mould for DotM (which they used in the Action set and Wave3 black redeco as well). But the bolt deco Bbee in wave 2 is the TF2 mould for some reason (which is what they used in the TRU scanning Legion 4-pack and the Walmart 3-pack).

This new mould of Bbee is like most other new moulds of existing character toys in the same size class - I just don't see the point of it. The old mould was good enough, and they even modified it for TF3 to allow it to hold a gun.
The most noticeable difference is the location of the front wheels on the arms... which probably makes it look more screen-accurate, but I don't expect accuracy from Legion class. They're just too small to be critical of that.
They've redone the legs, to make them look hollowed out - I prefer the TF2 version.
They kept the window-wing detail though, which gives it that distinct 'bee' look to Bumblebee.
Get it if you don't already have one of the many Legion Bbee toys already.
