Nintendo has done a good job of supporting Wiiu. The quantity and quality of Nintendo published exclusives is pretty impressive. Howevery, third party support didn't go as planned and that's not something Nintnedo can fix on the Wiiu so i'm eagerly awaiting NX. On a personal level I wouldn't care in fact I'd be happy to see Zelda U being fully moved to the NX since I'd be buying it at launch and think it would be even better for NX if the game was only available on NX.
I don't think you'll find too many of the Nintendo faithfull caring that Nintendo is already talking NX. In fact for me personally it creates some excitement for Nintendo's future during these dark times. The more casual family buyer of Wiiu doesn't educate themselves that much on future consoles so I don't see them caring.
