Anyway, we're missing the main point. GTAO PS4 servers are on it seems. Maybe they thought, fuck it: "we don't want a day-1 server death, lets just let the people who get it early, beta test it for the days leading up to release." People are transferring their characters fine and everything. I actually think for them, it's better they got it out of the way before the stampede arrives.
