Mad Max Trilogy soundtrack on vinyl

With track titles such as "Max Decides On Vengeance" and "Max Enters the Compound," the first two Mad Max soundtracks embody the movies' stark and ironic dystopia. Disc 3, of course, has "We Don't Need Another Hero." I have embedded the instrumental version here as a taster of
the forthcoming vinyl set, with Brian May, Maurice Jarre and Tina together at last.

For the first time ever, the original Mad Max trilogy of soundtracks have been combined into a stellar deluxe package designed by Marvel comic artist Tim Bradstreet (The Punisher, Blade). The outside three panels consist of all new original artwork while the inner panels display minis of the original jackets and the tracklisting. The color of the vinyl is Gray, Sand and Black respectively in keeping with the central colors of the new art panels. No more than 2000 units will be made and the trilogy will not be duplicated in another package.

It's up for preorders at $70 and will ship in April. I wonder: why doesn't it include Mad Max 4?
