The reason to think about it is because of what i saw what they made with the plattaform genre.
You can go with this line of tough: When you have a lot of certain kind of game(and good ones) exclusives on that plattaform, the people that buy that plattaform will have more interest in more games of this same type. Look at 360. It has the halo and gear of war ip. Then, microsoft made aggrements to have early acess to some dlc, and they became the to go plattaform for shooters in general.
Then, nitnedo tried the same with wiiu, but with the plattaform genre. Rayman was almost exclusive, lego undecover is exclusive too, they tried with sonic. Even today, we have prospect to recieve another plattaform game very soon: DKCTF. In matter of fact, fans of the plattaform genre will get a wiiu. This worked in some extent, since on wiiu rayman legens selled more. The problem: plataform genre don't sell console anymore. Die hard plattaform genre fans are a niche now, so it not going to change the console fortune.
But, the second genre that are really shaping up everyday better on wiiu is the action(non-shooter) genre. You see, action genre in japan is big. Even bigger than most of fps games. Then you look at what you have with wiiu. A zelda hd. W 101, they had even a ninja gaiden 3 exclusive edition for some time, remenber?
Then we look at future: Bayonetta 2. Zelda musou. Zelda U.
Do you see? They are trying more games on this genre, to make people buy the machine to get the better experience on those genre. Why would they fund bayonetta 2? Why would they lend zelda ip, one of the most valuable for then?
What do you think? It will work?
