Re: FoX Cinematic Universe
They already took a risk when they released First Class and now with the 2nd Wolverine movie. Deadpool and Silver Surfer were also in pre-development stage but they probably didn't go ahead to filming/production stage because they know Deadpool wouldn't outgross a X-Men film and Silver Surfer wouldn't outgross a Fantastic Four film.
I don't know why they should keep taking the risk again and again, when there's more potential for success with the original cast. That would be the same case with Fantastic Four if the reboot became successful.
And I said this a hundred of times, its rare for a spin-off to outgross the main/original series. Origins outgrossed X1, but if you adjust the ticket prices, it didn't.
