This statement needs some additional context. Yes, Yokoi wanted the most affordable design for GameBoy, but he ultimately did support Okada’s proposal. This matter boils down to nothing more than a difference in vision and should not tarnish his overall contribution which arguably made the GameBoy the success that it was.

That said: What was his contribution? Well, one if his major contributions was in making the system significantly less powerful and, in particular, being without color output. In doing such, Yokoi intended for the system (a.) to have a solid battery life and (b.) be sold at an affordable price. If it weren’t for Yokoi’s intense advocation on this matter, the system would’ve likely been in a situation very similar to the GearGear, a portable system which did output color at the cost of being over priced and with a very short battery life.

Matter of fact, had it not been for Yokoi scrapping together the GameBoy production fiasco after a fatal production error caused GB to temporarily be canned, there would have been no GameBoy. So, again, I don’t believe a single difference in vision should discredit Yokoi’s overwhelming contribution to the GameBoy’s massive success. (Need I remind you that this individual was solely responsible for setting up GameFreak with small projects to pump up funds, in order that they may produce a little know franchise called Pokémon?)

Agreed. Okada wasn't discrediting Yokoi and replacing an idea, but rather helping perfect the idea. This is true with the process of many collaborative art forms, including music and film.

That said, Okada is a name that should really be mentioned among Nintendo's greats, too.

So, if I were to give a "Mount Rushmore" or the four people most important in defining Nintendo, it would be Yokoi, Okada, Miyamoto, and Tezuka. And then there are really great people down the road the further represented the ideas of these four, perhaps in superior ways such as Koizumi and Iwata.

As a note, as designers/creative artists, I'm also a big fan of Tetsuya Takahashi (but that foes way back before his time with Nintendo) and Shigesato Itoi.

Probably not the greatest, but a lot of people either don't know or forget about him, so as someone who co-created and designed Zelda, and with his love of Lord of the Rings had a lot of influence on early Zelda (and early Zelda being my favourite Nintendo IP), was writer for Zelda II and director of A Link to the Past and Link's Awakening, my nod to Takashi Tezuka.

Tezuka is a legend for sure; he also directed Mario Bros 3 and World, as well as Yoshi's Island, so he was at the helm of some of the best games ever made.
