Blizzard finally got their Q&A segment out. Full video here : http://www.gamespot.com/videos/diabl.../2300-6420595/
Or some nice tidbits to take away...
Xbox One will have a day one patch to put it at 1080p, inline with the PS4. Remember that both will be running at 60 FPS still
Monster density has not been reduced from the PC levels. Which means there will be quite a few more enemies on screen versus the current console version.
360 owners will have to wait for the digital download version until Sept 16th... They can however still pick up a hard copy at normal release on Aug 19th.
Supposedly "new rules" have been added to lessen the effects of modding and to keep them within certain limits. Also, modded items will not transfer over (see 34:45 in the video).
Legendary gem will be added at a later date, TBD.
Supposedly able to kick / remove a player from the game trough your consoles "features". not quite sure how this will work yet though...
Edit: Update towards removing hacking / cheating. Most items with more than 10 item attributes were deleted upon loading the game with the newest TU. Item stacks that go beyond their standard stack sizes (tomes are 1000) seem to stay in game with no ill effect (tested up to 23000 in increments of 25 and saw no need to go further).
