CCP Cmdr Wang recently posted clarification on some of the beta concerns over at EVE Online forums:
Thank you for your interest regarding the DUST 514 Mordus’s Private Trials registration. I would like to take this opportunity to address some of the concerns raised in this thread.
With regards to the MPT availability, currently it is available In English for English speaking regions. So, if English is the official language in your country, you should be able to access DUST 514 Mordu’s Private Trials from the local PSN store in your area. We are, of course, working on localizing the client so that it becomes available in more regions for the Official Launch. So to recount, the DUST 514 Mordu's Private Trials will be in English only for English speaking regions, and our plan is to have localization for the following languages by Official Launch: English, French, Italian, German, Spanish and Japanese.
