Well. Hey wouldn't it be cool if we could have two Enterprises fight each other?
And that could be a possibility if it is indeed April's old Enterprise. It looks like the J.J. Enterprise is spiraling towards earth after it looks as though it has been in a pitch battle. I am wondering if a battle takes place between the moon and Earth. It does look like the other Enterprise looking ship is in a moons orbit.
Anthony Pascale over at Trekmovie has confirmed it is the Earths moon that the Enterprise looking ship is orbiting along with Kirk space diving towards it in a debris field. My bet is the debris is pieces of the J.J. Enterprise hull and it's deflector dish.
