Before IM3 came out SSC said they intended to visit all of the various Marks in 1/4... Don't know if they still intend to with at least 5 new highlighted Armours from the last movie.
Now, I know Legacey has done a 1/2 Mark V, and a 1/2 Mark VII, and my guess is that they have done 1/2s for all of the major Armours that have appeared... So it is hard to tell what will show up.
