Vader will be in it (and Han Solo may cameo)

The most recent rumor says that none other than Darth Vader will make an appearance in Rogue One, most likely in the third act, at the end of the big battle (battle teased by the concept art above). Who says that?

Making Star Wars, which has a great track with the rumors concerning the Star Wars Universe, says that the designers were asked to literally replicate the suit worn by the Sith in A New Hope. To what end, if not for a special appearance?

Other websites have also picked this up and continued saying that he is the reason why the battle proves to be a bloody one – Vader is supposedly going to destroy all the bounty hunters who stole the Death Star plans.

The new Han Solo is also expected to make an appearance, before his first solo flick (2018) – though this is a bit of a stretch, based on the fact that the studio is already searching for an actor. Nonetheless, if he will indeed appear, it will be just a small cameo from his part.
