I will agree on waiting a year or so. My Son bought a new F250 when they brought out the new 6.0 engine, even though I told him to wait and see if it had any bugs when they designed it.
He would not wait and got a lemon of a engine that broke down on three trips and he got rid of it after 18 months on the advice of a Ford dealership mechanic. Then Ford gets rid of the 6.0 engine due to design faults.
