That has nothing to do with point 1. How much do you think Dark Souls II would sell on Wii U? Who would buy it? Exactly. The statement in your link is absolutely justifiable and has nothing to do with 3rd parties being "biased against Nintendo".
Get a grip on reality.
It has everything to do with point 1. It proves that Nintendo wouldn't get all multiplatform games, even if their system was equal to others. Just look at the Wii U:
1) Electronic Arts never intended to put Dead Space 3 on it.
2) Square-Enix never intended to put Tomb Raider on it.
3) Take Two never intended to put Bioshock Infinite on it.
4) Konami never intended to put Castlevania: Lords of Shadow 2 on it.
That's already four publishers off the top of my head that denied ports before the Wii U went on sale, meaning that Wii U sales had zero influence on those decisions.
