Yup, looks like DC Comics has lost the rights to the real estate known as Krypton.
I haven't been reading Superman for some time. Has anyone noticed changes in the book that have been preparing for this? I had heard that Kandor was now on its own planet (but hadn't they done that back inthe 90's?)
On a side note, DC stills own the word kryptonite. But they have no idea where that rock came from.
