Possible Final List (keep your fingers crossed):
Archanubis: Retiring; he's decided to go run a saloon in some distant hub of the galaxy
Northclaw:

; Ain't that obvious?

He's also being promoted to the rank of Dragoon commander.
Celaeno:

- never hurts to try something new. (I always pick a rarity...)
Darkwylde:

- I believe that's G2/UNI Spacecase's alt, which is close enough to a Su-47 in appearance.
Kumiho:

- at least until a version of the Shadow Fox is added to the Decepticon alt roster at a later date.
Lohikaarme:

- close enough to the appearance of a wyvern.
Novacula:

- what can I say, Blackout's one of my fav. movie characters, despite the fact he doesn't speak
and is killed offScavendrill:

- Change can be a good thing.
Sea Wolf:

- Let's face it, I love this alt (at least until the Mosasledge appears in the con roster) and it fits his personality better. And it's a core alt for the cons!
Stratosphera:

- works in regards to her function
Venomstrike:

- I think he's the only one who isn't changing form.
Wingshadow:

- Sorry VP, Wingshadow likes how this one looks
Wreckage:

- Probably the only canon name I'm going to attempt to get for the team, and while I know that movie Wreckage's alt is in the Repair Tank alt roster for the cons, "Heavy Vehicle" seems to fit him better given his personality.
