http://www.pso-world.com/news/02487-pso2-jp-sega-id-registration-currently-region-blockedBasically, if your not in Japan and you already made an account, you're fine. But western players can no longer make new accounts for the Japanese servers as of the moment. So if you have any friends who you wanted to play the game with, but they didn't register yet, then you're out of luck.
So this pretty much confirms I'll be switching over to the western servers. I'll keep the Japanese account open just in case, but unless the Western servers are REALLY behind on content (don't really see it happening) or some of my friends just refuse to play on the Western Servers, I probably won't be coming back to the Japanese servers.
*edit*
Region lock lifted. That being said...
I like how people said they'd probably lift it, that this was just a test run, and that whatever they really wanted to implement was going to come later.
As in, whatever it is they actually intend to do is going to be bigger scale. Hopefully just region-locked downloads, but anything is possible at this point. We're not in the clear. Don't go spending a quazillion dollars on AC unless you're still okay with losing access to it.
Just be ready for the worst, is all. I'm not saying the worst will happen, but it's foolish to think we're safe now because of something that was entirely expected.
