Was there maybe a missed marketing opportunity with Avatar?

Just got out of the theater from watching Avatar again. Love that movie. But a thought did occur to me, maybe there was a missed marketing opportunity here? See, before they showed 3D trailers on the screen, they tell the audience to recycle their 3D glasses after the show, which is a mistake in my opinion. You should treat that object like a special memento instead. They should tell you, "save your glasses for the Blu-Ray 3D Edition in Spring." Or "Keep your 3D glasses for a discount off the video game." Or when the movie was out before Christmas, have Sony sponsor the glasses, so when they plug the Blu-Ray edition, it encourages people to buy PS3s in anticipation of watching movies that were meant to be seen in super high-def.

Instead, the labeling on the glasses says "Real D 3D," which is the biggest waste of precious real estate on the most quickly distributed souvenir ever.
