Right now, I doubt there's any ink on any contracts - or even any contracts. Just a lot of waiting and seeing and vague promises. I find it particularly pertinent that Neil Wilke's Digital Spy liveblog of the SDCC Who panel contains *both* a confident "I was told by insiders there would be a movie announcement and it would star X" and later on the same page "They have just announced that there's no movie being announced."

In other words, there's a whole lot of insider information being whispered... and it's all obviously worth the paper it's written on. (Which is why I'm taking the news of Torchwood's S4 renewal with enough salt to pickle me.)
