Is 'Star Trek 4' Being Written, And Are The Nerds Behind 'Beyond' Secretly Writing It?

Star Trek 4, the follow-up to this year's Star Trek Beyond, was confirmed in July by J.J Abrams. The man who rebooted the franchise on the big screen in 2009 and pushed it forward with 2013's Star Trek Into Darkness said it's "100 percent yes, and it's incredibly exciting." Although there's no release date or director yet, the signing of screenwriters J.D. Payne (an uncredited writer on Beyond) and Patrick McKay was announced days after Abrams' comment.

So what are Simon Pegg and Doug Jung doing in the tweet above, at the office of Bad Robot, Abrams' production company, which is back on board for Star Trek 4?
