Some Targets have taken to putting up a sign in their TF section regarding the "production delay" and are basically pointing the blame at Hasbro. I saw a pic of it on Seibertron's forums, but I haven't seen it locally. It doesn't make that much sense, since they'll have the G1 repaints soon, so maybe it's just that one Target.
I really can't blame Hasbro for playing it conservatively when it came to production numbers on these toys. Everyone from here to the Moon hated the robot designs when they first saw them, and Hasbro pays attention to that stuff.
But I still want my ******* Concept Bumblebee, goddamn it.
