As a side note, back in 2007 Marvel teamed up with IDW to do a Transformers/New Avengers crossover. Truthfully, it was just Marvel trying to cash in on the Transformers money train that was about to take off, because it was released around the time of the first movie.
The funny thing about it is that this story is supposed to be in the normal continuity of both series disavowing Spider-Mans previous encounter with the Transformers.
