“Sheldon misled you unfortunately; I do not even have an offer for JCVD to do Expendables 2. I am sorry; I believe Sheldon didn’t understand this himself.”
The Sheldon being referred to is Sheldon Lettich, the man who originally broke the story. Sheldon is Van Damme's friend and the man who directed him in such films as Double Impact and Lionheart. All of this information needs to be taken with a grain of salt. Jean-Claude Van Damme may end up being in Expendables 2, its a very strong possibility, just don't take anything as fact just yet.
