So the ps2 is holding us all back for new skins and huge new expansions with all new zones an new jobs. The game will eventually die if they stay going the way they are.(keeping everyone on same playing ground as ps2) SE now has a new dedicated team to XI, so that would lead me to believe they want to keep going with it. So what about the idea of having 2 versions of xi, one with the original servers for people that refuse to leave the ps2. These servers will continue on getting reskins and no new zones or jobs. (Maybe they can use the old servers that are being migrated)
Now there will also be new servers for pc/xbox/ps3 people to have the option to migrate to in order to enjoy new content. Now this may require another dedicated team to the ps2 people but it keeps everyone happy and playing. Maybe the ps2 people will see how well the game advanced and how fun it looks and decide to migrate to the newer systems.
