Face it Seagal will not be in EX3.
Why? Do you have a source? We don't know if he will be in it or not. The negotiations are still going. Sly offered Seagal a role and he will do it if the part fits. So Stallone is writing the characters right now...then he will show Seagal the character he has to play. Then Seagal will say NO or YES....
We should hear soon what his answer is.
