There are probably a lot of soiled seats in the panel room now, as most fans there wet themselves with excitement over all the new stuff shown.

Just about everything had rub signs on their concept art - not sure if they are coming back though (I will try to ask)

Legends class
G1 Optimus
G1 Starscream
G1 Prowl
G1 Megatron (proper G1 gun form - can even be held by MP Starscream)

Scout class
G1 Windcharger

Deluxe Class
Generations
Skullgrin - grey Darkmount redeco with G1 Skullgrin head
Scourge - stealth bomber, to complete the set of three movie Deceps in Deluxe form.
WFC Cliffjumper - Bumblebee redeco and new head
Thunderwing - similar Gen1 jet mode (Energon Megatron jet mode) WITH detatchable nose drone, similar to the actual Gen1 Thunderwing toy.
Tracks - even has the wings in car mode

Deluxe Class
HFTD
Tomahawk - and new head design shown
Terradive - also showed new head design for the later redeco
Mindset - Gen2 character (under Jhiaxus) using Hailstorm mould.
Fallback - can't get Outback name, but is that character, using Brawn mould

Maybe Generations, maybe HFTD
Gen1 Jazz - Gen1 form in both modes, including pop out speakers like in the cartoon.
Perceptor - Gen1 robot form, half-track vehicle alt-mode. Has shoulder cannon and flip open chest panel like Gen1 form. Redeco planned - Reflector.

Voyager
HFTD
(Blue) Fallen - Has a new head (show me your face scene), and will be a darker blue than the one in the display case.
Grapple - Universe Inferno mould with crane, new head and feet.
Highbrow - new Autobot twin-propellor plane in display case
Lugnut (I know someone here will be a happy little fanboy ) - similar to Lockdown, it is styled on the Animated version, with a more 'realistic' alt-mode.

PowerCore Combiners
2-pack
HeavyTread (Tank) w/ Groundspike (Autobot?)
Skyham(m)er (fighter jet) w/ Airlift (Decepticon)

5-pack
Steamhammer w/ Constructicons (construction vehicles of different colours)
Grimstone w/ Dinobots!!!! (dinosaurs - Grimstone is a Pachysaur (like JP Beast Wars Hardhead))
(not too Gen1 looking dino modes or colours)

Designer Aaron Archer then presented their story focus/mythology for the next several years (from where WFC and Exodus were born).
He showed us some of the first 13 (character art, no toys... at least not for a while).
Alpha Trion
Liege Maximo
Vector Prime
Prima (keeper/creator of the Matrix - Warrior of Light)
Megatronus (face is meant to look like the Decepticon logo - the 'god' that Megatron aspires to become)
The Fallen (once known as Megatronus - maybe the same character)

The rest are still a mystery (to us fans) at this time.
Each are 'Huge Epic Gods', so if a Toy is ever done for each, it will be big.

No more WFC toys are planned or expected, as they want to see how succesful the game is first. (which means at least a year minimum for more toys)

No Prime toys revealed - maybe not planning to release any when the show starts?
