The Diablo 3 website is set to receive an update "soon". We don't know what it could be, but Blizzard has posted a very vague image along with the line: "Coming soon to http://www.Diablo3.com"
So what could it be?
Back in May, before the launch of Diablo 3, Blizzard promised new Character Profiles would be added to the website. If this is indeed what it will be, character profiles will allow you to review all of your character information, share it with others, and check out the accomplishments of others playing the game.
A career tab will display all of your heroes, how far you’ve progressed in the Diablo 3 campaign, how many foes you’ve slain, the names and playtimes of your fallen Hardcore heroes, and more. A heroes tab will show off your equipment (including dyes, socketed gems, all equipment bonuses, etc.), your attributes and skills, the skills and equipment of your Followers, and more.
Another popular suggestion from fans seems to be a Diablo 3 armory. Looks like we'll just have to wait and see.
Meanwhile, the actual Diablo 3 game is still awaiting the arrival of PvP and Blizzard looking to create more end-game content to provide an alternative to the repetitive item hunt.
