The only thing I agree with this OP is that PS3 was a failure in profit and expanding its brand. Its good for gamers but bad for SONY.
And I think the 3DS was a necessary evil(?)/blunder so Nintendo can gain 3rd party support for the 3DS which may help for the next home console. Nintendo thinking they can win a gaming generation without 3rd party seems more of a hubris than thinking they need 3rd party. I'm not arguing about "quality" 3rd party games but the mindset that Nintendo thinks, because of the Wii, they can beat the whole industry without 3rd party because it received poor quality (in sales and "gamer's" quality). The 3DS focus on power is to regain 3rd party and develop better relations with them, hopefully, although the DS already recieved good 3rd party support.
This good relation may pay off for the next Nintendo home console.
