There is one more rumor about US/EU servers being only B2P (buy to play) with cash shop included, which kind of, considering other localization versions cash shops, beats the purpose of B2P...it's not like they're flooded with bots and gold spammers either (due to various game aspects). But then again this rumor is spread for the most part only by black-desert.com, and they say that US/EU servers site will be http://www.blackdesertonline.com , which I can't confirm or deny, though suspiciously enough that site is as poorly designed as their own, you can really do a lot better within 10 minutes of random site generating platform of your choice even without knowing how to code or draw...seriously look yourself how it looks at the time of posting this thread:

it's just ridiculous... but the site's domain name is owned by Ji Cheol Ryu which supposedly previously worked on DAUM but now works at OnNet Europe, though he could come back, so I wouldn't be so sure if that's truth or a big hoax, let's wait a bit more and find it out.
P.S. So I've dug out a bit deeply and seems like the site is real deal, and servers most likely won't be B2P only: "There has been talk from PA of the possibility of there being both F2P servers and Pay to Play servers. More info is sure to come in the future."
P.P.S. B2P only confirmed.
