There is going to be a beta test for the new Hot Shots Golf game between May 26-28. You can download an entry application on the Japanese PSN store. Also when they announced this part of the reason they are doing the beta is because they are doing a worldwide server. This is the first official announcement from Clap Hanz that the servers would be combined and is great news for us. Now we should be able to find a game at any time. People mentioned this in the release date announcement thread but I figured "new news, new thread". Here is a link with all the info and a link to the download ticket on the Japanese store.
