Well from what I've heard now Namco Bandai won't be bringing any more of the .hack games over. I'm sorry I don't have a direct source for this since I just saw this on facebook along with a quote from Hiroshi Matsuyama the president of CyberConnect2 who make the .hack series. The quote is "The .hack games are only coming out in Japan now. If you want the games to come over, ask Namco Bandai Games America on Facebook". Granted the problem with this is Namco Bandai Games America doesn't have a wall to tell them on so people are going to the Namco Bandai page to tell them. So I'm going to link you to that page if you want to tell them. Honestly the .hack series is my favorite game series ever and I seriously want them to come over here. They all sold well with the G.U. series selling almost 3 million total worldwide. So if you want to say anything to them then here is the link for Namco Bandai's wall.

If you don't know about the series then don't do anything unless you plan on getting any of them. Sorry if that sounds rude but it's supposed to be everyone showing they will buy the next game if it comes over and that statement is kinda meaningless if you are just saying that and don't care either way.
EDIT: Ok here's a mild source for it.
