Almost finished? I recall Josh saying they still needed two years..
No he didn't. He said however that the game was ready to show, and ol' Ferg also said the game felt like it was finished. I'd say Obsidian maybe needed another 3/4 or 1 year for completion.
Either way, maybe it isn't so dead as we believe. There's still a slight chance the F:NV team might continue working on it after it ships.
