The black solid figure in the videogame might be a reference to the main protagonist of Rise of Robots, a solid blue robot, he has the same basic design.
Not Noticing
The autobots are not noticing anything
1: They don't notice Wasp as Bumblebee with purple eyes and no white pupils.
2: They don't notice Wasp as Bumblebee acting weird. (like saying bumblebot)
3: Optimus, Ratchet, Jetstorm, and Jetfire dont notice each others autobot symbols.
They are really letting things slide.
