Well no it doesn't always work that way, since DOFP fans been discussing things that fox must be thinking or doing and have been completely wrong, one was that they were using DOFP to see which cast the audience wanted for apocalypse when really they already knew what cast they were using, people were just insisting that after FC they were testing the waters with DOFP when chances are no thats likely not what was going on there.
same with everything about deadpool, thats gonna go on for a while where people speculate how fox will milk the deadpool machine like saying how they will put wolverine and deadpool together in wolverine 3 because people will wanna see that and fox want money! well still waiting on that announcement but giving how fox have been with this franchise since 2009 i don't think there is any point comparing them to marvel, WB or even sony because i have seen no sign of the copycat attitude of WB, the desperation of SONY or whatever marvel does.
