Undisclosed? Have you seen the shit that is ASM 1 & 2? Sony basically wanted control over the MCU and damn Feige and Marvel Studios. Glad Disney did not agree to this. let Sony keep pumping out bad movies and losing money while Marvel just keeps getting all the royalty checks from merchandising from said movies.
I believe that ASM2 was the worst performing Spider-Man movie under Sony...and was still very profitable.
So if Sony can create an entire universe of comic book movies in which they are producing high grossing, profitable movies, as opposed to giving it back Marvel...why would they?
I'm not saying ASM2 was good. But was it worse than Thor/Thor 2? Meh.
With Sony, Spider-Man will be a focus. If Marvel gets the rights back, he'll be yet another successful franchise Marvel/Disney needs to find a spot for in their busy lineups. We'll never get some of the more interesting ideas Sony is thinking of (Venom/Carnage, Sinister Six).
As a Spidey fan, I just want Sony to get a better writer/directer/producer and pump out good Spidey-universe movies.
