A new EW article about Star Trek confirms at least part of that by saying officially that the trailer for Star Trek XI will come out on that day with that movie. Combine that with the AICN article and the Transformer: Revenge of the Fallen trailer rumors and I think my interpretation is confirmed.
Hopefully in a few weeks exact details will start to come out but now I have three good reasons to look forward to the new James Bond movie - the movie, TF2 trailer and ST trailer.
Along with the article, you can find stills from the Star Trek movie, writer comments and producer comments.
