Warners' "Year of Superman" site is up. They've got a cool intro movie and a calendar of releasees (not very specific, it just breaks it down into quarters). Looks like the Kirk Alyn serials are indeed on the way in Quarter 4, along with the last two seasons of TAOS and, if I'm reading it right, the Donner version of Superman II, available as a single purchase outside of that mega-box. Boy, I hope so!
