On Blu-Ray Options

So I've seen a lot of ads saying Jim Cameron's Avatar came out today, but I'm pretty sure I saw it on sale this past Tuesday. Maybe that was just the DVD or something, I don't really know.

What I do know is I have to buy this movie eventually, just because I really did enjoy it that much. The question becomes do I buy it now, on pretty, pretty Blu-Ray, or do I wait and buy it a few months down the line when it probably gets released in 3D? Will 3D matter on a home theater system? Was the movie only awesome because I saw it in 3D on a giant IMAX screen?

Screw it, I'll probably just pick up copies of Ferngully and Pocahontas for $6 each. Same difference
