LEGO Teases a Surprise on Facebook

Today LEGO posted the photo below teasing “Something big” 4.86 times larger than the London Bus box by volume. Speculation is that it’s the new Millennium Falcon UCS set we’re all so anxious to buy.

In the comments on Facebook, someone claims you can see through the packaging in one of the corners, but I don’t see anything.

What do you think it is?
