They've said many times that the time just wasn't right to make them.
Note, they were planning on slowly introducing more constructicons till they could make a full Devastator.

 

Awesome to see these guys...

-Rodimus Minor- pretty much just as awesome as I was expecting him to be. I really like that they kept his bow weapon. Alt-mode isn't perfect, but it does look nice. He's a must-have.

-Arcee- Still looks good, and is still a must-have.

-HD Bumblebee & Golfire Grimlock- both look nice, but I don't think I'll be getting either one, tbh.

-Freeway Jazz- he's looking good. There's a chance I'll get him, but basically just to kitbash as a Decepticon.

-Cybertronian Ratchet- looks good, but I think I'll wait and get Ironhide if I get this mold at all. I like the inclusion of the paddles. they help finish of his alt-mode nicely.

Too bad they didn't put Wingblade Prime and Blackout out there too, but oh well. They are two other figures that are must-haves, and I'm thinking about getting two Blackout's too.

 

If our 3D printer project works, I'll be making a custom head for "Fugitive Bumblebee" - as Wasp, of course...  

 

does the backpack come off of hd bumblebee so he can just be the car?

 

Yes it does.

 

got to have them all and my wallet is already sueing me for divorce XD damn you hasbro

 

I can't wait for Rodimus & Acree... And ofcourse Wingblade Prime

 

I like that Hot Rod..

 

Should've made the bitch sign a prenup!
