The OP has a point. Kojima announced a megaton that most would swear up n down to be a Sony Excl, at a Microsoft event. That's big news especially considering that E3 is followed Worldwide.

Hey wait a minute.
First of all, thirdparties have no responsibility towards either Sony, Microsoft or Nintendo. They most likely go where the money is to be made.

Second, Microsoft bought themselves into Sony´s thirdpartysupport? Possibly, but what do you think Sony has been doing since they started all the way back with PS1? They sure as hell did "steal" a lot of thirdpartysupport from Nintendo after SNES.

Sony has in my opinion always been about hardwareprestanda, huge thirdpartysupport and succesful marketing. Now they have competition from Microsoft in this regard. They cater to the same market.

I think its very disrespectful ... he is going against the ninja ' death before dishonor ' ... should have been a ps3 exclusive ... id LAUGH if after E3 he says it was a joke, and laughed at M$ ... think that would be funny

Sony "stole" them with the use of other means. Superior technology and opportunities for third parties.

I don't feel comfortable with the way Kojima presented the new metal gear solid game. It's like those movies when the best player on the underdog team is persuaded to join the richer elite team despite the history he's had the the underdogs ( Sony wasn't always the underdog however), my respect for Kojima has gone down a little but I fully understand the situation,he wasn't the only decision maker.

But this is business and if Sony returns back to it's glory then Kojima will run back to the Sony train with hat in hand and again everyone else will get the left overs.

If he isn't answerable to Sony then i would say that doing business  or announcing a deal with another company is in no way disrespectful.  Furthermore i'm sure Sony has been aware of this for quite some time.

Kojimo is THE man behind the MGS series, how would it have looked if he hadn't been present at the announcement of the game?  I think people would have assumed that since the game wasn't on a Sony platform and he wasn't present that the game didn't have his full backing which equals bad PR for everyone involved in the game.

he's cheating on you. get back at him by sleeping with his sister! Or something

Anyway, 3rd parties can develop for whoever they want, they don't owe anyone anything

Why shooting Kojima ?

Sony is the one who showed lack of respects for the gamers... and Microsoft did well this generation.

Besides, Kojima won't abandon his fanbase for sure.

Epic could also present a game for the Playstation. Why not ?

Anyhow, it is only a problem in fanboy's mind...

We're not talking about legal obligations , we're fully aware of the fact that Kojima or any other 3rd party can develop for any console they choose,

It's Kojima's history with the Playstation brand that has caused some disapointment amongst the playstation audience, it's like all those years of Metal Gear Solid games on the Playstation meant nothing , in the period of 15 mins he neglected around a decade of history.

OP, would it have been acceptable to you if Kojima had announced the game for the PS3 first and the 360 later?
