Black Isle - Returns?

The return of Black Isle Studios has been announced but previous members don't seem to know much about it. For example, Chris Avellone on Twitter 'I know nothing about the Black Isle Studio news announcement, doesn't involve me or Obsidian... or well, anyone that I know. ;)' and Brian Fargo 'I just read that Interplay is bringing back Black Isle. Hmmm... Not enough info for me to comment'. The sparse website is here.
