Interesting that Seasons will be coming to the PS4/Xbox One Ultimate Evil Edition (beginning with Season 10). I think they finally realized that the source of most hacked items and characters were created on prior gen consoles where the game saves were then exported, and then imported into the newer consoles. Since seasonal characters will only be available for creation on PS4/Xbox One (both of which have not been fully jailbroken which would pave the way towards cracking the game save encryption and thus allow the type of editing that happened on prior gen consoles), that should keep that part of the game as legitimate as can be on those consoles.
The other pet (besides the mini butcher) for the anniversary event is a “moo cow”. The clutter from crafting materials will be getting their own tab (Chinese, Japanese, and Korean game designers could take some lessons here even though I know that design is often intentional to force cash shop inventory expansions).
The armory will also complete the action combat arcade-dification of the game (don’t get me wrong, it is a great quality of life feature but having this level of load out will really push the point about how the game has strayed further from its ARPG roots).
The press kit also shows how much smaller the actual design team (at the lead level) is compared to before as well as pulling new producers from other Blizzard franchises (the rest are probably working at the conceptual stage on that unannounced Diablo project).
