Eh, no way it's going away from Wii - Nintendo would like it better there than on 3DS and SE wouldn't backstab Nintendo by putting it on PS3 after the Western success of DQIX and the massive Western potential for DQX.
Anyhow, it better be coming soon and be more awesome than DQIX. And it better be followed by DQVII/VIII remakes and DQ-DQVI on VC, :D.
Yeah as we all know Square Enix have never backstabber Nintend in the past ;)
