Since Red Alert isn't being labelled as 'Cybertron' like the other WFC toys, it is likely to be the Classics toy that was only released in the Henkei line, like the Thrust toy that will be in the first wave of Generations.

For those not checking the link, it lists the four Wave 3 figures for Generations -
Cybertron Megatron (new)
Cybertron Soundwave (new)
Red Alert (redeco if Henkei Alert)
Darkmount (new)
