As a Wii U owner, the leaked Switch line up is very weak

Yes, a few of the games are ports, but as others above have said, there are other, new games that will be released that will probably equate to a better launch lineup than the Wii U's. Also, we can't expect the launch to have the same volume as the Wii U's whole library, there'll be many new games beyond launch
