That looks absolutely amazing. Individually articulated fingers on the hands? new feet? Definitely all over that. I reckon Smokescreen also makes the most of that Prowl mould, he looks much more suited to the style.
Yes, I didn't notice there was an individual Tentakill at first - the way he's positioned and photographed makes him look like he's one of Piranacon's legs. But he's not! And, aye, a Moonracer-reuse he could be, but hard to tell.
Nevertheless, these are exciting! All of the molds look great, and Piranacon is a brilliantly beefy bad boy (or should that be tuna-steak-y?). My one hope is that the beast-mode jaws of those that have them will be moveable - that was one of my biggest disappointment with the Predacons, the fact they couldn't do that; you have an animal that can snarl, you want it to be able to snarl properly!
The interesting question is now the "Targetmaster" feature is going to work. From the looks of the photos it seems like the individual bot plugs into the top of Piranacon's hand, rather than being gripped. I can't quite make it out, but I'm wondering if it'll be that the figure's combiner connector is what plugs in there - that'd make sense to me. And leads rise to my one fear - that the figures used as the arms won't have enough tension in them to be able to actually hold the gun up.
Those thighs are going to need fillers, but apart from that he looks excellent. I'd love to know what's going on here; Takara keep showing us figures that Hasbro don't seem to want to: Star Convoy, Armada Prime, Seacons, the other power dashers, whereas Hasbro are showing us Galactic Man and co. I thought in this new era of unified releases that everyone is doing the same stuff, but it doesn't look like it.
Hasbro put up Star Convoy for preorder almost as soon as it was announced. And Phil thinks that Armada Prime is the Optimus from the Siege follow-up line, if not the next Commander figure that was shown by accident/miscommunication, and I'm inclined to agree. Takara has been radio silent on that, too.
