Check out dakkadakka blood bowl thread in news section for more upcoming releases and rumours.
Also check out talkfantasyfootball forum for more in depth discussion.
And finally, check out the new book Blood Bowl Almanac, really great compendium of most stuff released so far (White Dwarf articles, Death Zone 1 and 2, Teams of Legends, extra weather tables). It is missing the Blitzmania stuff, all the various cards (from decks, events, white dwarf etc) and a few special star players (Grak & Crumbleberry which they managed to include photo of, but no rules or info that they're not really available to most players). It is also missing the new weather effects for goblin and elf pitch (guess they were made after the book was finished).
