So it's the imax ratio, eh? It played both ways but I guess they have to pick one or the other. The blu of Dark Knight also followed their imax version, (where the ratio switched back and forth). I think Cameron was hoping there'd be more big IMAX screens by now.

Unrated/Extended cuts is a whole new annoying thing, but I guess it's a tacky fact of life now. If you live in the US and want to go to the store and buy a blu-ray of the theatrical Watchmen or Miami Vice (Michael Mann is pretty guilty of going all Lucas on everything) or several others you're just out of luck. At least with Cameron you always have a choice. I'm more worried about other movies fate on blu, like the original version of Apocalypse Now or The Warriors.
