http://news.xbox.com/2014/06/xbox-one-july-update-previewLooks like the new update is starting to roll out, so we should all have it in any day now. See above for details.
Snapping achievements is the biggest new addition and I gotta say that's pretty sweet. The fact that you can quickly see how close you are is really nice. In the video they demo Dead Rising 3 and that was a good choice... there are lots of "Kill 100's number of Zombies with X weapon" achievements in that game.... this new feature is perfect for seeing how much more you have to go while you destroy the undead.
I also like the option to "get achievement help" and it will instantly take you to the web search (usually resulting in youtube clips) on how to do it. I rarely use the web to help with beating bosses, but I have no problem if the web can help me get some extra achievement points. Still not 100% sure why I care about achievements, but I do!
