Ah, the translation error hits once again! It looks like the original blog from Japan that posted up the discussion with Square-Enix’s Yoichi Wada made a mistake in their transcript. Mr. Wada’s comments had nothing to do with Wii U. This would make sense with the report from earlier, which indicated that Square-Enix was looking into working on Wii U launch titles.
Once again, there was no talk of adding Wii U compatibility to Dragon Quest X. With that said, the Wii U is backwards compatible with the Wii, so at least you’ll be able to use Wii u to play the game!
