Avatar Teaser Trailer Coming Soon?

Could the first teaser trailer for James Cameron's Sci-Fi 3D epic Avatar be on its way? MarketSaw posted these very convincing photos of a batch of packaged 35mm film trailers. Fox's The Day The Earth Stood Still hits theaters on December 12th, could the teaser be attached to that film? I can't imagine that Cameron would want to release an Avatar trailer not in 3D, would he? Some have pointed out that the lengthy running time listed on the boxes might point to it being a fake.
