Fallout 3 might still live:
Obsidian Entertainment (
http://www.obsidianent.com/index.html) was formed late last year from mainly BIS staff. They have a total of 21 ex-BIS developers and along with Silver Style are the front runners in a bid to acquire the rights from Interplay, assuming Interplay will sell the rights. Obsidian also formalised partnership agreements with Bioware last year, so even if they do not produce FO3, they have RPG expertise galore, and we can be looking forward to quality RPG's once more. Obsidian has not released a game to date.
Silver Style, Troika and a few other companies have also succeeded in acquiring one or two BIS developers.
