I don't know if there any collectors of steelbook cases here but StudioCanal UK are to release 4 of the Studio Ghibli titles in steelbooks later this year. Full details on Blu-ray.com
here.
The titles in question are
My Neighbour Totoro,
Ponyo,
Howl's Moving Castle and
Nausicaä of the Valley of the Wind. I would imagine that these will be Region B locked as per their usual practice.
