I feel like Nintendo is just getting started with this system and very great things are to come. As with any new system, It takes a while to work the kinks out and learn how to get the most out of a system.
Usually the first games that come out for a system don't push the system to its max, time is needed for the developers, even 1st parties, to learn how to work with the system.
To me, Mario Brothers Wii U is stunning, but Mario World 3D will look even better, and so on and so on.
Who knows what these secret games will be, a new way to play IPs we already know, an old way to play new IPs, or a new way to play new IPs ... Only time will tell, but to me it sounds exciting at the very least.
