While the Wii U line-up is missing many titles coming to Xbox 360 and PS3 in the same period, titles like Scribblenauts, Rayman Legends, Monster Hunter, LEGO City Undercover, and Pikmin 3 should interest existing owners and perhaps tempt fence-sitters to take the plunge on the new console. We would like to see a few more games announced for Q2 though.
