Ultra Magnus: I actually really like the figure, I just don't give a fig about Shattered Glass. So count me in on that one, I guess. I'm pre-registered, so I AM getting the set, just don't think I'll be keeping them all. I actually started cooking up ideas for alternate uses for some of the characters, and I like the idea of using him as one of the older Primes (maybe one who's been named, maybe not) who's become sort of a cross between a Ringwraith and the Old Knight from Indiana Jones and the Last Crusade. He's been trapped somewhere... maybe guarding something? ...for millenia, and now he's just a Spark-powered ghost/spirit/whatever wearing physical armor. Kinda creepy, but why the hell else is he translucent?
Treadshot: I think that's a SHARP looking figure, nice colors on a great mold with a decent new head. But seriously, a reference to a character that only appeared in a Universe 1.0 Battle in a Box set?? That's obscurity for the sake of it. I like the idea of simply using him as a new figure of Armada Sideswipe. The original was one of the biggest turds in TF history, so he deserves an update. Hot Shot got one, so why not?
Soundwave: Just... no. What little I know of SG Soundwave, he sounds like a really stupid character. The mold choice is terrible (OMFG Ironhide's got a window chest like Soundwave so it's meant to be!!!) and it's a pretty crap mold to begin with. There's not one damn official character I could re-purpose him as, and I don't care to come up with a new one for it. This one's got the least chance of taking up permanent residence with me.
Tracks: You mean Road Rage? She'll be more than happy on my Classics shelf.

Overlord: Le SIGH. Really?? This could NOT have been their first choice of a mold. More likely they conceived the set, found out their first choice wouldn't work, and had to go with a backup because one way or another, they were already committed to Overlord. The biggest disappointment here, by far. Universe Silverbolt would have been my pick.
Metalhawk: Reserving judgment for a big pic, but it's the mold I would have expected. They could have used some other random jet-bot and ignored the shell, I guess, but I doubt that would have felt much like Metalhawk.
Octo-Punch: Nice idea, a new head would have helped immensely. Execution is just plain lame. Very little chance of any character identification on looks alone. And the paint apps on the existing head are awful.
And if we continue going with Seibertron's list, which has been pretty accurate so far?
Kick-Off: Well, it's a better use of the mold than Treadshot is. Kick-Off keeps popping up here and there in the official fiction, so it'll be nice to have a new figure. Unless he's Shattered Glass, then BOOO!!
SG Swindle: Uh... ok. Depends on what they homage, I guess. Really relaxing that non-re-use rule aren't they?
SG Junkions: Damn it all, I want to hate this idea, but I really like it! That's the VERY first SG idea that really intrigues me, and I think they'd look awesome in the Insecticon color schemes! What are they, a vicious tribe of savages? Maybe cannibals? I'm kind of digging on this...
