Here's my theory:
Marvel is getting all of its properties back and rebooting them ("The Incredible Hulk" and the just-announced "Punisher", for example) so that they can exist the shared Avengers Movie Universe they are creating. Sony must have still have the rights for more Spider-man movies, so they're going to reboot it while they still can so that when the rights defer back to Marvel, Marvel will be less likely to reboot it for the third time in a decade and Sony can still bank on their existing movies instead of having them erased by what would amount to be the "Official Marvel" version.
This is only my theory, but I think it makes sense business-wise.

When you say Marvel, you mean Disney ? (If I don't mistake I remember they bought Marvel...)
