This is actually RoS but without the contents of RoS unlocked yet. I think Crusader items will be dropping just like in the PTR. This is the best method to do it having everything loaded and ready to go for RoS to launch quite smoothly. We might still get a patch or two before RoS is out.
Yeah, it gives them a month to find any bugs involved with actually patching the live database versus starting clean like PTR and copying in characters from a snapshot of the live DB. Should make RoS launch more of s 'switch on the new content' rather than a 'launch event' like D3V was. Much like they've done with WoW the last two expansions.
That's one of the tricks you learn when you get older...I simply refuse to get annoyed about something I can do nothing about. The servers will be up when Blizzard brings them up, and being angry on the forums won't make it go any faster. Being angry just makes me a pain to be around for a while, and nothing more.
Just let go of it, go play something else, and check every few hours, or go to bed when it's time, and check it tomorrow.
