Spider-man movie musings

Okay, Spider-Man 2 comes out next week, and me and one of my co-workers (whose name really is Thor) were talking about it. We started out with how well the casting was done, not only for this movie but for the first one. Molina was an excellent choice for Doc Ock, even if (according to Thor) they didn't use the green and orange jumpsuit costume from the comic book.

But we got to thinking...

Spider-Man made a lot of money. Spider-Man 2 stands to make a lot of money, as most other movie companies are not putting any big films against it for the first week or so. So it stands to reason that they are at least going to make one more movie after this, and in fact, they may ride this horse for as far as it goes.

So that got me and Thor to talking. On the (not very big) assumption that there will be a third Spider-Man movie, who would be the villain in that one?
