I think a few things could lead to Wii U being more successful.
1.) Dragon Quest XI being shared between 3DS/Wii U like DQX (assuming this is a more traditional game).
2.) Pokken Tournament being a huge success.
3.) Youkai Watch for Wii U
4.) Another Monster Hunter
5.) Xenoblade being a huge success in Japan
I think it's more safe to assume PS4 will win though.
