I am sure there a like a million threads about the Shuttle Attack, but I have a question that always got me thinking while watching the scene, when the Cons hijacked the shuttle, and went awol on the Autobots and killing without mercy and without hesitation (basically it was 2 years of rage build inside them). Right before Ironhide and Ratchet returned fire, why didn't they contacted Autobot City about a possible incoming Decepticon attack? That way the Autobots stationed on Earth, would have had plenty of time to get ready and have Autobot City transformed in time. Metroplex's transformation cog would never had gotten damaged and they would have planned a better counter attack. I know this was just a way to get rid of the old toys and introduce the new toys, but let's eliminate the whole "old toys/new toys thing" for a moment, wouldn't the Autobots have a better chance?
