Just wanted to let everyone know and I am going to put this in as many ways possible.
The Launch of GTA Online will depend on XBL and PSN Management.
Rockstar has no control of when Xbox live and PSN updates, the 'patch' to enable GTAO will depend on what time MS and Sony decide to update.
It is possible that certain regions will have the update/access before others, for ex. UK could have it before the U.S. or vice versa because XBL and PSN is run by different people in different regions, they update at different times.
Please take this into consideration before you start getting mad at Rockstar if GTAO does not launch when you expect it.
Can't wait to see everyone online! Practice up until then!
