Finally, Wii's future line-up looked terribly bleak. Let's see if things get better. We may get Xenoblade's release date.

In fairness, it's only the start of the year that's bleak/dead which NSMB and WF+ mostly covered for, the year looks fairly well supported by first party efforts starting from the middle of the year. We've known about Xenoblade, Mom, The Last Story, VS software (whatever it is), and Zelda Wii for some time, of which the ones that may not end up big are at least Japan focussed.
