Terrible news. Capcom announced a couple of months ago in their forum of all places that the XBLA version of Talisman is canceled. Sheesh, at least they could've issued a press release.
I'm pretty sure Blood Bowl is being developed by someone else.
Actually I'm thinking since FFG has the license/deal with GW and FFG recently announced it was doing Wings of War and Tide of Iron for XBLA (and Citadels for iPhone) that maybe they shut down the Capcom project and plan on doing it themselves.
