Ever since Nintendo had that unprofitable year, I've seen people are saying they're going to case to exist in like 5 years unless they go third party.
Both are highly unlikely. Nintendo will probably never go third party because that's what sells their consoles. I don't buy a Wii to play multi-platform games like CoD (I hate CoD though, but it's just an example), I buy a Wii to play Mario Kart, Super Smash Bros, Metroid, Kirby, etc.
If they did go 3rd party, I'm guessing they'd probably earn a ton of money over a short span, but it would die off soon after, and they'd be worse off overall.
