I watch the daily show and colbert report every day and I've noticed for the past couple weeks at least there has been a strange cube thing that pops up on screen during their commercials for Southpark or Important Things. I don't know what it's supposed to be and from what I've read neither does anyone else it seems.

The reason I'm thinking this might be a rotf tie in though is because it seemed that this started appearing around the time when the first trailers for the movie started coming out. Plus, it's a weird, alien looking cube. Where else do we really see weird alien cube things?
Just speculation, but who knows?
