Square Enix/Yahoo announcement is Sengoku browser game

Mind that mindblowing announcement Square Enix and Yahoo! had for today that would "change Japanese history"? Yeah, about that...

Turns out it was just a browser-based game for the Sengoku series, known as Sengoku IXA.

And unlike most browser-based Sengoku games in Japan, where you have to pay for them, this one is free!

The official site's here, just in case you're curious.

Thanks, Kotaku, AGB and mington.
