I'm glad you saw it! I found myself googling a lot of stuff afterwards, and I found a pretty plausible fan theory that Peter B. Parker is actually "our" Spiderman--that is, the one from "our" universe.

By the way, the B. apparently stands for Benjamin. Also, although I didn't notice it, some people caught that at the flash image of this Peter's wedding to Mary Jane, he steps on a glass. Hmmmm ....
