A question that repeats in my brain is "why the hell does this jazz exist the last one was the best ever pretty sure."  RTS Jazz was a great mold, and pretty definitively Jazz, and probably couldn't be topped for "G1 Jazz toy" until a Masterpiece comes out at some point, and maybe not even then.

Of course, the answer I have to shove back in that question's face is, "Fall of Cybertron Jazz isn't G1 Jazz."  I mean, sure, this design has been repurposed AS G1 Jazz in the current IDW comics, and it looks more like a G1 Jazz than a design from the universe he's intended to be from, but it's still the case.  This is the "Aligned" continuity Jazz, the universe Transformers Prime is located in, as well as the War for Cybertron/Fall of Cybertron video games.  This is the Jazz who was Orion Pax's best friend before the war.  Organizationally, he'd go on my Prime shelf.  He's technically a new character.

But still, comparisons still battle in my mind, not unlike when I got Prime Wheeljack not so long after G1 Wheeljack.  And then,  y'know, the size.  RTS Jazz was a pretty friggin' huge Deluxe, and FOC Jazz is a pretty small Deluxe.  He's no Scout, but he's definitely less massive.  And while RTS Jazz's transformation is pretty standard and been-there-done-that, FOC Jazz is streamlined even more.  His entire car mode roof and rear is pretty much a shell that Automorphs onto his back, with his legs tucking underneath.  The only manual transforming you really have to do is folding down his feet and rotating his arms at the elbow.

Things I do really like, however: He's blue!  The Jazz of my childhood was white and blue, thanks in part to the Marvel Comics coloring practices of the times, as well as the Pretender and Action Master toys.  And so a Jazz with blues instead of blacks hits me right in the nostalgia.

And, yeah, he's fairly simple, but at least he's not goddamn WFC Bumblebee.  That toy should die in a fire.
