I think Feige and co would be foolish to pass up the opportunity to include Venom in their MCU. It’s potential huge money in the bank that they could have.
Besides, we already know that Marvel Studios has given Sony permission to use their characters - Iron Man being a prime example. Time will tell if Sony’s Version of the MCU will be able to join the MCU.
As long as they retain complete creative control. Venom will one day be in a MCU film, and most likely it will be Tom Hardy’s version, but Marvel Studios wants complete control when writing the story -that includes Venom.
The general consensus (among the die hard fans, Marvel Studios’ alumni) with Ryan Reynolds as Deadpool has been extended to Tom Hardy as Venom. Money talks. And Venom has beaten Marvel Studios’ one solo origin efforts (Captain America, Thor, Ant Man) with Venom and you can be sure that the results speak for themselves and are resounding in the minds of Marvel Studios’ executives.
