At this point i would take the servers down and have a test server. There they could test & provide feedback(voting system for different in-game systems).
The lodestone would provide frequent updates and details of the content being worked on. A series of bi-weekly video updates going around the office and showing off a few things.
Taking many existing systems from the previous entries and modifying them slightly in a unique or fresh way. Previewing new updates periodically and having test sessions done.
Finally, i would promote the game "Revamped", "Revised" & "Reborn" (whatever) and have a release along with Ps3 once the game was ready.
Loyal fans who purchased the game previously would be rewarded with special/unique titles, armor in appreciation & patience, an extra free month once the game went live, & a limited time deal that their subscription would be lowered for every person($1) they could get to play the game ($5 decrease limit).
Upon release i would also promote special campaigns to draw people in. These would include special items & EXP rate increases on set days in the week/month.
