During the Rainbow Six: Siege Season 3 Pro League at Katowice it was confirmed that there will be a Year 2 of DLC content. While no other exact details were given aside from there being a Season 2 or Year 2 of content depending on how it will be officially worded we can guess what will be included. This is based on what we received during the first year of the season content since I was lucky to receive the Gold package from Ubisoft. This content will run throughout 2017 containing four map drops along with a series of new gadgets and two operators that fit within the location of the maps. I'm also assuming there will be fixes and improvements throughout the year as we've continued to see that happening during this first year. I'll take a guess that the content will also be free as it was before and that the old season pass might carry over that grants early access to the maps. All that aside, I am looking forward to playing more Siege as the game has been quite great over the last year. The only disappointing aspect of this is that a full Rainbow Six title is now further away.
