More of the same is definitely something people want sometimes -- but other people want something new (or more-of-the-same of something else that hasn't been done as much, e.g. a sequel in a smaller series). The article is about (among other things) the stagnation and general tendency of big developers towards increasingly-stale safe bets.

Mario Kart is an example of that: Nintendo is perfectly willing to make more-of-the-same for Mario Kart, but when asked in interviews about the possibility of a new F-Zero, the answer has generally been "we don't want to just release more of the same, we want to come up with some new twist on it". It's not about novelty (or if it is, their standards for novelty are inconsistent), it's about one being a cash cow and the other not.
