We’re pleased to introduce the Battle.net account -- a brand-new way for players to manage their Blizzard Entertainment games, make online Blizzard store purchases, log in to World of Warcraft, and more using just one set of login information.
World of Warcraft players now have the option to create a Battle.net account, merge a World of Warcraft account (or multiple accounts) with it, and begin logging in to the game, the Armory, and the forums using their new Battle.net account login information.

Some of the benefits of the Battle.net account include:
At this time, signing up is completely optional -- but if you’re interested in taking advantage of the benefits of the Battle.net account today, check out the FAQ for more information, or create an account now.

So, there you have it.
Not so hothot news, but there's more!
The same news can be found on StarcraftWire. However, they note that the authenticator keys you currently have for your WoW accounts will all be useable for all your battle.net games! Isn't that sweet? Also, if you currently have 4-5 of the things (1 for each wow account), you'll only need a single one from this point on. Sadly though, WoW can't be merged into your battle.net account yet if you're living in the EU.... Like myself.. /sigh
As for those battle.net account wide achievements, those are definitely in the works and have been announced quite some time ago already. I figure posting it here again should serve as a nice reminder.
Basically, you'll be able to inspect each other's battle.net account (or look it up on a website) and see another player's world of warcraft achievements. As well, you'll be able to see the number of Starcraft games he won, and the highest level diablo 2 hardcore character / ladder position he has ever achieved. These are just examples, but no doubt there will be plenty other options coming!
