Nintendo had an ambitious line-up of games to be released before the end of March, 2013 (which marks the end of the Wii U’s launch window), and it turns out that ambition was a little too good to be true.
Pikmin 3, The Wonderful 101, Game & Wario, and Wii Fit U have all been delayed, with a new release time frame of the “first half of the year”. That’s vague enough though that I think we will see at least one or two of these titles released closer to Christmas.
