"Launch Window" basically means November and December of 2012 for the Wii U and March 2017 for the Switch. The Wii U games above all sold at least half a million at retail. Switch games hve either sold half a million or are likely to do so. Multiplatform games are in italics.
Long Story short, the Switch has the upper hand. The Wii U landscape was barren after launch until summer was well underway, whereas the Switch has had a constant stream of notable first party titles. And although the Wii U was meant to encourage third party support, it doesn't have a major lead in that category. The impact of ZombiU, Monster Hunter, Rayman, and Disney Infinity is roughly on par with Bomberman, Minecraft, Sonic, and Skyrim.
