Sony stated that the 20 exclusives coming to PS4 are made by FIRST PARTY STUDIOS.
That's like saying Nintendo is releasing 18 1st party titles in the Wii U's first year. If they did that I'm sure you would be on your knees crying tears of joy. That list that you put out doesn't even compare to what MS showed at E3. I'm sure we will see exclusive shovelware on PS4 and Xbone as well.
And let's not even include all the de facto 3rd party exclusives for the PS4 and Xbone since those games aren't even releasing on Wii U. You really have to be blindfolded at this point to see that the Wii U isn't stacking up to the it's big brothers.
