I don't know if this is considered news, but the Smokescreen and Bluestreak busts are now available separately for pre-order exclusively on toyrocket.com. Before they were only available as a set of three along with Prowl. Here's the link: http://www.toyrocket.com/Statues-and-Busts-C2101.aspx And, yes, I pre-ordered Smokescreen.
Update: BBTS now has these. But why are they the same price?! I was hoping if(when!) BBTS put them up for preorder, that they'd be cheaper than ToyRocket! Especially since the rest of BBTS's Diamond Select busts are around $50! I guess they're being produced in smaller numbers? Heck, I don't know... http://www.bigbadtoystore.com/bbts/menu.aspx?menu=526&company=17
I just went ahead and bought the 3-bust package from ToyRocket. It's $10 cheaper and the shipping is cheaper. Making it cheaper WITH shipping than BBTS's prices without shipping. Oh, and ToyRocket also took off that 'pay up front' on the listing, so it doesn't get charged till it comes in.
