Is Miyamoto's take on new IP's right?

The Division was just an example, but it's more about the general idea that new character = new IP which I don't agree with. Something like Dante's Inferno would probably be a better example.

Which would you prefer?
a) 5 shooters with different characters that all play similarly.
b) 5 games with the same group of character that play nothing alike.

Different IP's have settings, temperament and gameplay tweaks that set them apart from one another. Look at the difference between Uncharted and Last of Us. Similar mechanics, yet two totally different games.
