Berserker looks like the same SUV robot in the highway sequence from Transformers: Dark of the Moon. The 2011 toy was called Crankcase but he was unnamed for the movie. So either this is yet another dead Decepticon returning, a twin, or Hasbro is merging old and new Transformers into the line. Takara is doing a 10th anniversary re-release of previous movie toys but they are using the same molds from then while this looks like a redesign to fit the simplified transformation goal. Between Barricade and Berserker I can't help but wonder if part of the plot involves dead Decepticons being revived (or rebuilt by humans). The idea would also have the benefit of saving production a whole lot of money as ILM could re-use the previous movie's existing CGI files. After human salaries, creating a new Transformer from scratch to be photo real and transformable is probably the most expensive costs for the production each time.
If want to see more, here is a video slide show of the same toys.
