I must say i chuckle when I read Yoshi's posts or hear him comment that the marketing team will be unhappy that he has shown us some new art or screen grabs without them knowing. From the outside the marketing team dont seem to be doing too much right now to promote this game.
I was talking to my partner on the way to work and we thought that Square should consider starting to market ARR for PS3 players.
Square could easily release the End of an Era/New Beginning trailers on the Playstation store, perhaps create a couple of free static XMB XIV themes, maybe even charge for some moogle or chocobo dynamic XMB themes.
When phase 4 open beta starts, Square and Sony could perhaps open up PS3 beta access to Playstation Plus users (currently being offered by CCP for Dust 514) to try out the game and spread the word.
Regular posts on Sony's playstation blogs to keep the PS community informed of ARR's development progress would also be helpful to stir up some interest.
Just a thought anyway, as i know there are many people who are playing other online RPG's on playstation 3 such as White Knight Chronicles 2 and DCUO that are looking forward to a final fantasy MMO on playstation.
