People suggest that Nintendo should go third party before the others because Nintendo has the most successful intellectual property with the potential to sell well on other consoles.  Also, most game sales on Nintendo consoles are Nintendo games (73% for the WiiU, 60% for the Wii).  Most game sales on XBox/Sony consoles are third party games.

Like ive said, you cant just assume that Nintendo IP will do vastly better by being on PS/XB. We have seen many times that bigger install base does not automatically mean bigger sales.

Mario 64, Galaxy & 3D Land have sold around 10-12  million, thats on devices with 30-100 million install bases. Sunshine, Galaxy 2 & 3D World have also sold similar amounts.

Pokemon has sold pretty consistent for about 15 years now, the mainline titles have sold about 15-17 million while remakes have sold about 10-12 million & expansions have sold about 6-8 million. Thats on devices with 60-155 million install bases.

Animal Crossing has sold a similar amount on DS & 3DS, devices with an 80+ million gap.

Metroid II, Super Metroid, Fusion, Zero Mission, Prime 2, Prime 3, Hunters, Other M have all sold around 1.5 million give or take on devices ranging from 20-155 million. Prime is the best selling in the series on a 20 million install base.

With the exception of the first title, Kirby has sold a pretty consistent 2 million give or take on GB/NES/SNES/N64/GBA/DS/Wii/3DS.

The Legend of Zelda, Ocarina of Time, Twilight Princess all sold about 7 million despite vastly different install bases. Zelda II, Link to the Past, Majoras Mask, Wind Waker, Skyward Sword all sold near 4 million.

Then we also have to take into account demographics. According to this site, about 3/4 of all retail sales on PS4/XBO come from the shooter, sports & action genres. Can we really expect the online shooter/open world action/annual sports crowd to start buying things like Kirby, Mario Party, Pikmin, Donkey Kong, Animal Crossing, Rhythm Heaven, Fossil Fighters, Paper Mario, Pokemon Mystery Dungeon, Yoshi, Captain Toad, etc?

I honestly dont see most Nintendo games having a big enough increase for it to be worthwhile. Ya some games like mainline Mario, Pokemon, Smash Bros, Zelda, Mario Kart might do really well but is that worth it if most of their titles see little to no increase?

it's not that complicated. Nintendo would have to adapt to the fanbases of the playstation, xbox and pc if it wanted their games to sell.  Focus on their mainline games (instead of so many spin offs and kid game shovelware) and create new IPs that better fit the other bases. 

Unlikely. You underestimate how stubborn Nintendo is (and sometimes rightfully so, the industry would suck if everyone did the same thing). 

Well, it would still be nintendo but with less kid games and more of the kind of games it's own fans want to play (more mainline nintendo games) and what other gamers want to (new IPs focused more on adults).
