The real conspiracy is that the head of R* is the alien that piloted the ship in that Roswell incident way back in the day. Since that time, he has remained hidden, searching for a way to insinuate himself (itself?) into our society and he found it in R* and saw that he (it?) could take control of the most moldable minds (gamers).
He (it?) has succeeded. By creating the hypnotic juggernaut that is GTA V and leading gamers along with a proverbial carrot (Heists), they are taking our money (cash cards) and our minds (causing everybody to focus on the one thing they can't have) and soon they will take over the world because this is the will of the alien CEO.
You need to break free of this influence. You need to see all of this for what it is - like the Matrix, it's a method of control, and the aliens are winning!
Forget about heists! Stop focusing on them! You have fallen into the alien trap and it's up to you to escape it!
Take control of your minds and your lives! The aliens WANT you to wait for something that doesn't even have a concrete release date! They WANT you clamoring for this content, bitching about something inconsequential so that you are completely distracted from the real threat!
tl;dr: Get a life. Stop worrying about heists and do something with yourself.
