Honestly I don't expect atmosphere till Christmas, November the earliest and it will not have backup loader. I know you can find information on how it will release sooner than that but just like in the professional game development; delays are inevitable. Also Team Xecuter wouldn't release a product in June if they thought that atmosphere was in any way ready for public release. They wouldn't waste the money developing it if a free solution was on the Horizon. Till then it's still a waiting game.
