I've never been attached to this franchise, but DQX seems like some squeenix execs imperative as opposed to a ... good idea. An mmo is a huge investment/risk, a huge prolonged commitment afterwards, and the genre requirements of online persistence and subscription fees I would think is at some odds with the wider audience of the franchise. Hearing about a WiiU version makes more sense in some ways, I have more faith that its online capabilities will be better, but will it need to be reigned back to maintain parity with the og wii users?
I kinda had DQX pegged all along as a NSMBWii type sequel, where you take an accessible franchise and make an excellent polished rendition with a modern sheen. Dragon Quest sure did throw a curveball this gen.
