I do wonder if a point has been or is being planned to discontinue Dragon Quest X on the Wii to allow for a better focus on PC and Wii U. You can see the limitations of the PlayStation 3 hampering some aspects of Final Fantasy 14: A Realm Reborn, either specifically to the PS3 version or to all versions. Square Enix has talked about this subject with FF14-2 with the PlayStation 4 version of the game entering its public beta test phase.
MMORPGs is a relatively new ground for consoles (keep in mind, there is a PS2 version of Final Fantasy 11), so I'm curious as to how publishers, developers, and platform holders will manage them.
