The mystery behind "Grand Theft Auto 5" possibly getting or not getting any upcoming single player downloadable content (DLC) continues to deepen with the latest revelations of one of the game's actors.

In a Facebook post, Ned Luke, the man who lends his voice to "Grand Theft Auto 5's" Michael De Santa said that he knows "nothing" about plans to create new single player DLC for the game, VG 247 reported.

Luke added that he does not even know when single player DLC might be arriving for the game, or even if that kind of content is still in the works for "Grand Theft Auto 5."

One thing Luke did reveal is that he and fellow "Grand Theft Auto 5" actors Shawn Fonteno and Steven Ogg will be dropping in on some conventions this year.

Luke did not identify exactly which conventions they would be paying a visit to.

It's also unclear if Rockstar is in some way involved in the trio's planned convention tour. According to Luke, they are simply going on tour to meet up with some fans.

Still, the trio going on a convention tour together could be taken as a hint that there is something in store for "Grand Theft Auto 5" in the near future, but whether or not that involves single player DLC remains unknown.

Rumors about new single player DLC coming to the game began to pick up steam last week after Fonteno posted a picture of himself decked out in motion capture gear on Instagram, Games Radar+ reported.

Fonteno did not reveal exactly why he was in a motion capture suit, so fans are yet again left to guess as to what significance the photo may actually have.

It's worth noting that Rockstar has already said that they will be focusing more on developing on "GTA Online" content as opposed to single player DLC.

More news about "Grand Theft Auto 5" and the new content coming to the game should be made available in the future.
