Unfortunately, reality soon set in. They're doing it as a pricy, sixty dollar hardcover in their Archives line. Amazon listing.
I think somebody at DC missed the bit about these being kid's comics. The really crazy thing is that they have recently started up a line of 100-page $8 books reprinting recent superhero comics, and that's a line that makes sense for the material, even more than those big, thick Showcase Presents books. Look, Sugar & Spike is wonderful and silly, but it is for children. Sixty-dollar hardcovers are not. Get your heads together, DC!
