"In its attempt to stay competitive with Sega, the convergence machines Nintendo today criticizes, were once the waters Nintendo intentionally sailed. (Although, with the drama that would soon follow, it's no surprise Nintendo developed a bias against them.)"

Please read again :) I said "market" in my first post... Stay calm, take a breath, nobody's going to hurt your Sony, they are still fine in other areas (like game console lately). 

Also, innovation is a matter of oppion, right? I mean you are one of the first to shit on Microsoft fans because they find innovation in the Xbox One...

And nintendo still regret things with sony going so wrong... Sony probably think the same about MS approach in the past.

You have some twisted ideas by thinking that corporate entities have any kind of emotion (spite, regret, etc). Business is business to them....

Companies still have shareholders and boards of directors... and even tough some despise them, they have human emotions... And regret wasn't used as a sentiment, but in the meaning of knowing they "created" their best rival on that field.

And you'll find that businessmen who invest/bet with their emotions don't stay businessmen for long...Besides, they go where the money is, so if another venture opened up that's more opportunity for them. There's no regret...

whatever you think... and about companies having "emotions", that is a language artifice, altough companies have "persona" described by their objectives, phillosophy and the general posture of directive board.

And about ventures, that is not what most senior board members do, that would be more prey bird behavior... like the equity admin that keep complain about sony not selling out some of its part so he can have quick cash.

Policies do not equal emotions.Microsoft and Sony don't have policies to be snide, or vengeful to those who have done them wrong elsewhere. If that were the case, Sony's laptop industry would have gone kaput, you wouldn't see many BluRay players supported in Windows, and Nintendo would have released the SNES with limited supply of SPC700 chips. Business finds itself better off unhindered because of other conflicts. Despite what the majority think, Nintendo and Sony DID patch up their relationship between the 1991 CES and the next gen...

As for your second argument, you're not exactly thinking into it too much, are you? I can point you to a LOT of executives that have moved between Nintendo/Sony/Microsoft/Sega as well as other members of the game industry. There's no single handed "devotion" to a business (unless of course you're the owner/creator, but businesses as big as these rarely do..). You could see Kaz working at Nintendo, or Reggie working at Microsoft. The only ones that would have meltdowns over it would be the diehard fans... 

I know they are in good terms. You still seems to think I ment regret as pissed, I wasn't. But Ninty certainly would preffer not having sony as competitor during PS1 and PS2, and Sony would preffer not having to bleed on PS3 because of X360 fierce competition.

You are talking about hired executives, and without knowing japanese culture to think Kaz would work for Ninty for a bigger paycheck while Sony still breaths... about american staff they have no aliance or loyalty to company. That is why their investors are birds of prey and not the japanese ones...
