It seems abundantly clear to me that Rockstar took the easy way out and announced GTA for next gen early in order to shirk their responsibilities to keep developing for current gen. Through either arrogance or incompetence, they have completely bungled this game and lied to buyers promising heists for over nine months. Furthermore, it's been over one month since any content was released at all. This is shocking since Rockstar famously promised heists affirmatively (yet again) by the end of spring. All they had to do to make up for their failure was to release 3 new t-shirts, a re-skinned car, and a copycat rifle this week or last and many would've forgotten and kept blindly playing. But no, either through their arrogance or complete ineptitude, Rockstar is silent.
Now this isn't to say that current gen won't get new content but I wouldn't be surprised if the game releases on PS4/XBone before we see it. That's how long off it will be. This company is a joke. They should be held to task for their lies to consumers like other gaming companies have by the community.
