In a brief press release sent out tonight, Sony announced plans to "fully restore" services everywhere but Japan, Hong Kong, and South Korea. Additional details about each region's "Welcome Back" package (like, we assume, how to get it) will be announced soon.
As for the strange timing of this press release: it was issued from Tokyo, and thus timed for Japan but ... Japan is one of the three places that isn't affected by this news. Just something to think about as you're reading this at like 1 AM.
Update: Still up? Go browse the PlayStation Store! The PlayStation Blog details a bunch of new content available on the now-active store, including Wizardry: The Labyrinth of Lost Souls on PS3, the Turbografx-16 classics Alien Crush, Bomberman '94 and Bonk's Adventure on both PSP and PS3, and Sega Rally Online Arcade. There's also a single-player demo for MotorStorm: Apocalypse. There's ... a lot to take in. What you won't be taking in yet is the Welcome Back stuff: it's " currently in the final stages of testing."
