Blizzard is currently working on the two much anticipated games StarCraft II and Diablo III, now Blizzard has confirmed Battle.net 2.0 will feature:
* Excellent Ping
* Channels and Chat in-game
* Ladders and Rankings, secured against cheating.
* Extended stats, with possibility to see who D/C etc
* AMM-type Matchmaking
* Avatars, Images and Icons to represent yourself
* Diablo III Hardcore mode
* Friends/Ignore Lists with advanced management (see accounts below)
* Clan Support
* Automated Tournaments
Achievements
Just like in WoW, Achievements will be added to Diablo III and StarCraft II. Achievements such as "Win 100 StarCraft II games", or "Level your character to 100" are the new way of playing online and will be recorded on Account basis. Blizzard have explained that all games' Achievements will give a score that stacks to give you a "Blizzard level". Whether these features will be available only for new games, or all Blizzard's Battle.net games is unknown but it seems likely they will only be available in new releases. A preview of this system can be found in World of WarCraft, where testing is now commencing in the Wrath of the Lich King Beta.
Besides being entertaining, the purpose is also to bring people in to the multiplayer game, as the Achievements will only be available online where they can be checked against cheating. It should be more fun online, even solo. Trading and co-op is just a bonus, and Jay Wilson has even said that Diablo III won't even contain any other networking functionality besides Battle.net.
In-Game Voice Chat
Especially mentioned for StarCraft II, but also a very likely feature in other games is VoIP (Voice over IP) or "Voice Chat". The technology is already implemented in WoW, and has been promised as an example of what will come with Battle.net. It probably won't replace Ventrilo/TeamSpeak for the active gamers, but a great new way to chat for those who don't wish to use a third party program.
