No one company is *that* important to the overall industry.
Any one of Sony/MS/Nintendo could go away and the industry would still do OK. Nintendo is a little more unique perhaps in that their heritage and history are closely tied to the game industry, they focus most on family friendly product in an industry overwhelmingly targeting almost everything at teenage males, etc, and Mario is still the best known video game character in the world.
If Sony or MS dropped out, a company like Samsung could easily move in and likely offer something fairly similar, so what they do is not all that important either.
To be fair to Nintendo also it's a little bit of a high bar to set to expect every platform they release to completely revolutionize the industry. The fact is in each of the three previous decades 80s/90s/2000s ... Nintendo over the course of 10 years brought many new things to the table ... the birth of really the modern console with the NES (d-pad/third party licensees/etc.), the 3D revoultion of th 1990s they contributed greatly to with Super Mario 64, the analog stick, rumble pak, and even GoldenEye (really the first big console FPS with emphasis on multiplayer). In the 2000s they were first to touchscreen gaming (sorry Apple) and motion gaming too.
Sony/MS are basically just refining the same formula over and over again which is of the "game console for the 16-30 year old male trying to push gaming to be more like Hollywood movies schtick". Which is fine, but I think it's kinda unfair to single Nintendo out in this instance.
