No, really, they tweeted that. They, meaning the developers of Final Fantasy XI, tweeted from their Japanese account with the accompanying image above and said, “What the…something begins…!?”
I do not normally report on something as flimsy as this, but when it comes to the FFXI development team, any information is a bomb-shell. They are notorious for being extremely tight-lipped outside of their normal releases of information prior to version updates. This cryptic tweet and image could mean that the once-talked about port to the Vita is happening or simply that Seekers of Adoulin (the upcoming expansion) has essentially gone gold. The screens in the image do appear to be taken in the new areas being added, making the latter claim a tad more viable.
Final Fantasy XI: Seekers of Adoulin will be released for the PS2 (Japan Only), Xbox 360, and PC on March 26th, 2013. It will the last officially licensed PS2 game ever made.
