So lets get this straight. The OP has a picture of GT5 in his profile, and he's posting a blog from someone who shares his opinion that Forza 3 is garbage, and that its "wrong" of a developer to spout off like Turn 10 is.  Even though he's a GT fanboy and would hate Forza, even if it was the greatest racing game of all time. 

Is the point of the thread to trash FZ3 and Turn 10? I'm failing to see what you are trying to accomplish by posting this. The thread title is misleading since, in essence, the company is doing anything but sabotaging themselves. You and I both know that if anything, what they are doing is generating more buzz that will effectively result in more sales. The blogger himself is a moron since he's citing the demo as example.

Biased thread is biased. 

Some people are really starting to freak out over forza 3, looks like turn 10 has the competition scared.

does anyone in the real world actually make the decision to buy or not buy games based on a companies arrogance?
Or is this just an internet forum phenomenon?

Just the interwebz.  Not many of the public even knows that Turn 10 has been talking about the game.  The internet is a poor indication of how a product will do, most of the time.

Awwwww...It's always the little guys who run their mouth. Funny how PD was never inclined to respond to anything Turn 10 had to say, it's as if Turn 10 wasn't even worth it. If this article turns out to be the general concensus for the hardcore racers then that's a lot of repect gone from the fans and any respect at all from the better developer PD.

Who said they're not gonna buy the game because of Turn 10's arrogance?

My granny said she disagrees with the cockpit view. It's perfect for her.

She said the other game's cockpit view is too far behind that it's not realistic for her.

Notice that this comes up shortly after we find out GT5 is delayed (Again)... Expect many more articles like this over the next couple months... It is a FUD tactic...

The only thing I agree with is that development studios should not take shots (veiled or unveiled) at other development studios. The rest is fanboy craziness. Both racers will be great... One is shipping earlier then the other which gives it an advantage, especially since it is during the holiday season.

Delayed? when was the first officially announced release date?

NJ5, so you worked at MS?...what was your job there?
