Several new details was recently revealed via an interview Rockstar had with website Vulture.
In terms of size, the Xbox One version requires 89GB of free space while the PS4 version requires 105GB of free space on the hard drive.
In terms of gameplay length, Rockstar estimates it will take around 65 hours to complete.
And in terms of negative backlash, Rockstar is currently denying earlier claims they made of pushing 100 work weeks for crunch time in order to finish the game on time.
Also the reason why they've stopped bringing in big name actors for their games is due to Rockstar souring on the idea after dealing with several bad incidents in the past.
