I spend about 75% of gaming time, and all my media time on my xbox, so having 4k games and 4k bluray is a lot of value out of the box. I only use my PC for PC exclusives, I have no interest in FPS on KB/M, I just play strategy games and CRPGs on PC. I'll use the 1X for all my multiplats, so having the best console versions of those is a big plus. Xbox controller is by far my favorite, use my elite every day for more than a year.
Looking forward a lot for Cuphead, LOTR, FM7, Battlefront, and Crackdown this fall. Skipping Destiny 2 after being burned hard by Bungie on 1, Anthem looks a lot better. Bungie isn't interested in supporting its xbox fanbase, so I'm not really concerned with supporting them back. Next year I look forward to Sea of Thieves and RDR2 in 4k.
Getting native 4k feels like more of a generation jump to me than the PS360 to current gen, so all around can't wait to get day 1.
