The FLAGG is truly inspired. It takes the playset concept to a striking level, especially with the opening deck and front launch bays in the hull. It is a shame they will probably never release one, but it is beautiful.
I really, really, really like the repurposed ROC Pit as a cobra mobile base. Having a large rocket launcher and a deck that can fit 2 Hiss tanks with a bunch of missile pods shows what a little change can do to make an average toy into a great one.
Finally, on a personal note. I don't get Hasbro's reluctance to do a crossover line with Tranformes and GI Joe. They are both Hasbro properties so there is no licensing issue. They have had apparent success with Star Wars and Marvel "transformers". So why not Joe? Make sure they are cross branded as "Transformers" and I think you would have a successful line. Instead we keep getting just little teases like SDCC Starscream and the could have been Baroness/Ravage.
