A thought occurred to me after reading this train wreck of a thread:

Hasbro said back at BotCon that War for Cybertron was part of Transformers: Prime's continuity, and many people scoffed. Some are angry that their beloved G1-looking video game is officially not a G1 game at all, which apparently lessens their enjoyment of the game or something.
Anyway, the game and the cartoon don't fit together, but the WFC novel and the Prime cartoon were based on the same story bible Hasbro created.
It is clear that they meant that Prime and WFC are under a single continuity family, like Generation 1 (and everything else in Transformers) has loads of different continuities that don't fit together at all, but never the less fit under the same banner.
