On June 4th of this year Mad Max: Beyond Thunderdome debuts on blu-ray. It will be part of a trilogy package which will include, obviously, Mad Max 1 & 2. Or you will be able to buy the last two films separately. (If memory serves MGM/UA owns Mad Mad 1 while Warner owns the last two.) Unknown whether the first two films will get a remastering or what sort of extras come with the discs. Apparently there will be a limited edition tin case packaging for the trilogy.

Amazon is taking pre-orders for the trilogy. At the moment it doesn't look like its the limited edition version.

And sometime later this year Mad Max 4 hits theaters with Tom Hardy (aka Bane) taking over the role from Mel Gibson.
