Going off of memory, here's what is left to come out from that big leaked list:
Leader Megatron
Voyager Brainstorm
Deluxe Arcee and Chromia
Legends Gnaw w/ Gnash
I may be forgetting something. We'll probably also see things like Legends Gears & Acid Storm, Windblade, AOE sludge, snarl & helicpter Drift in person as well. Hopefully we'll see some concept art of what they're cooking up for next year, as Hasbro confirmed at...Toyfair? that they're already working on Generations 2015 & 2016 ideas
