you guys mentioned in the stream that PC just recently got Marni's Stones and here is the patch notes from when PC got them. PC did just get the Greater Marni's Stones, but those can come after Drieghan for xbox. 

For the TL DR: February 14th, 2018 

My suggestion for you guys on release date, do it the next week after Kamasylve's release date. This way, it gives you time to focus on bugs and other unforeseen issues and add these in that next patch. 

As a PC player by the time Kamasylve comes around you need the general public to be 220+ AP level 60 - 61, with about 1,500 skill points +.
