Sure, if their pre-development phase is already over it's probably not a huge stretch to assume the world redesign would come around Spring 2012?

I think Summer will be quite a critical phase for them. There can't be too much they need to do anymore at that point, assuming server, engine, area, UI and combat overhauls are finished. We'll probably have, say, 6 or 8 raids at that point as well which should be plenty for the PS3 users.
