I think steelbook is inevitable for this release just as it was for 1st movie. Beside rumors also suggests steelbook release for it.
This came just in right time since i wanted to bought steelbooks for 2-4 parts of Jaws but will now do just 3 and 4.
Beside all steelbooks for 2nd movie had that factory brown mark across front page... not to mention price for steelbook for 2nd movie is bananaz.
