It's a no surprise, lot of 3rd party games got cancelled on the wii u due to their hardware limited and very hard to developed on, kinda like the PS3. Nintendo next console[s] should be more powerful and more PC-like so developers in general can easily port their games on it.
I think the Japanese need to step up their techs. Not just Nintendo but Sony, Bandai Namco and others major japanese companies as well. They should learn from hugely successful companies like VALVE, Microsoft (not xbox1 tho) Apple, Samsung, Google, Disney, etc.
