edit: Hmm, it says the 14th(?). That's odd because I refresh that page every 20 minutes or so... maybe my browser is uber-caching. Sorry, if it's been discussed.
i saw that yesterday...sent a note off with my carrier pidgeon to inform my friends who don't have the internet. they've known since midnight last night.
and no your browser is not uber caching, don't worry. the date shown is the date the news topic was added to the steam web site.
