Strange how all this stuff and unfortunate occurrences is happening to major 3rd party players during a period where all of this consolidation is going on (bethesda woes, activision cracks at the seams) . A leak of this magnitude (if real) will no doubt have major implications financially on rock * (i hope not) but it does seem a bit weird to me, I mean what are the chances that some random joe(s) are skilled enough to hack into their servers? Rock * has previously been in a very strong independent state but the outcome could affect them to a point where they may possibly have to consider selling (depending on how much damage this causes them in the future...) I don't wont to sound too much like a tin foil hat but it does seem odd, lol.
On another note the compressed videos in the OP dont do much justice, IMO it looks pretty good and this is coming from someone who doesn't stan GTA series. It looks about as next gen as you can get for an open world game on the scale GTA6 will probably be on.
