Some of those games weren't even made by Nintendo, like Eternal Darkness, Hotel Dusk and Last Story. And of the ones that were, only Pikmin and Xenoblade have proven to be any good.
One of the biggest problems with Nintendo is they always come up with cool gameplay ideas, but then shackle to them to old tired series that have been ran into the ground with mediocre games like Mario and Zelda instead of using them to try and grow their newer ip into something special. Let's hope they actually do something with Xenoblade instead of letting it go to waste.
Most of Sony's and nearly all of Microsoft's IPs aren't done by internally owned studios either.
All of these are studios wholly owned and operated by Sony, many of which are working on brand new ip. When it comes to creating and growing valuable ip that sells consoles, Sony does a far better job than Ninteno currently does, who seem content on just releasing more rehashes, remakes, and spin-offs.

I don't know anything about Xbox so can't comment on that.
Zelda is also pretty immune from the experimentation, that peripheral tie in game and four swords (which is still Zelda, just with more friends hitting eachother) not withstanding.
It's still gotten very stale. The most recent Zelda games are two remakes (Ocarina and Wind Waker, with a Majora's Mask remake being considered), a nostalgia cash-grab (Link to the Past 2), and three very dumbed down sequels with awful gimmicky controls (Spirit Tracks, Phantom Hourglass, Skyward Sword).
