Even if third party sales were much much better on Wii U, it would probably be left out by most future AAA-multiplatform-games.
PS4, XBO and most gaming PCs have 5 GB RAM available for games, Wii U has 1 GB available for games. Developers won't restrict the minimal RAM for their level design to one fifth just to include the Wii U.
When 360 and PS3 support dies, Wii U support dies too.
