I jst been thinking today while I was at work today. Wondering why the Twins are not back, even if Micheal Bay says in an interview they are his favorite because he wanted humouris robots. Also, the Wreckers appearance are rednecks. So I thought the reason why the Twins are not in the movie are because of the Wreckers. those Redneck Autobots have got to look like they have humour in them. I can imagine Leadfoot being the burpping type, Topspin using his claws on his arm to scratch him butt and all three of them being the fartting type.
