IM, IAL & a few others were early releases for Steelbooks, i'm afraid (in my opinion) that as now confirmed some of these are now getting re-released, the exclusivity & collectability of SB's has long since gone..
I don't think any new releases will generate the kind of money that have been seen on the aforementioned titles.
Plus gambling on whether they will arrive unmarked / damaged is another point to consider. By the sounds of the one mentioned, there's no way that will ever sell for what it was purchased for..
Just my humble opinion
