I thought I would gather all the Blizzcon News on Diablo 3 into one thread so you should come here for all your Diablo Blizzcon needs! Enjoy!

Diablo 3 trailer unveils new demonic villain


Diablo 3 has “something like 2.8 trillion builds”
The focus on the design team is on viable builds, not optimal ones. Wilson admits that some players will always seek out the most powerful combinations, but points out that, unlike World of Warcraft, there’s no guild to represent or raid roles to optimise for. In Diablo 3, the aim is that “you can play the character you want to play at max level, and not be beholden to anyone.”

Diablo 3: 70% of items appear beyond normal difficulty
A team of Diablo 3 devs hit the main stage at Blizzcon to talk about Diablo 3′s difficulty modes. The differences between Normal, Nightmare, Hell and Inferno difficulties are important for anyone looking to get near the level 60 cap, but it’s surprising just how different enemies and loot will be on higher difficulties. In fact, Blizzard revealed that 70% of the game’s loot won’t even appear in Normal mode.

Diablo 3 gets team deathmatch, achievements and battle standards
Achievements unlock new parts and designs for your character’s standard. This flagpole is designed to be a way to show off your character’s prowess without the need for an overly-long sword or ornate codpieces. Story achievements add extra tassles and accessories to the banner, hardcore achievements let you customise the base. A high level standard was shown during the presentation, rising from a hoard of gold and gems, steeped in ribbons and arcane designs. These standards will be visible in the game world. When playing in co-op you can fast travel to your companion in the field by clicking on their standard.

Kind of remind me of Baal

That cinimatic made me so stupid happy.

I was pretty confused with the skill system, no skill points and you can have only a handful of skills at one time. I think they spoke about how you will only be able to change it in-town later on (previously any time while skill menu is up). I don't mind sharing some loot that n00b members needs but if its auction-able i'm for the latter (doubles are ok) :)

That is still subject to change, but switching skills in town shouldn't be that big of a deal since you will have the stone of recall early-on.

gotta say, D3 may well absorb my brain when it drops....
