Blizzard has launched a new preview page outlining some fo the new features that the new Battle.net will offer for Starcraft and potentially for other Blizzard IPs.

What has really gotten our attention is the RealID feature that will allow you to keep track of your friends across every realm (yes cross realm chat is a feature)  and every game Blizzard offers.  The other insteresting feature is that it offers a built in forum for mods makers, community created content as well as full access to the Blizzard forums.
