I'm sure most people that own a ps3 that are GT fans will get GT5, but in order for this to be considered a "killer app" it will have to convince people that don't have a ps3, to buy a ps3 to play gt5.
If the people who bought PS3's did so in order to play GT5, it's alredy served as a kiler app, even if the game never releases!
Sure it is (discussing GT competition)...
Okay, yes, things are getting muddled. Forza is competition for GT. It's on a cheaper platform. I don't refute any of this, as it's all true. My point was the GT franchise is curently bigger than just a game, whereas I think Forza is just a game. THus the worth of GT to PS3 can't really be viewed as 'it's a racer in a market with other racers.' It's the same for KZ versus Halo. Anyone who said 'Halo is facing competition with Killzone 2' back in the day would have missed the point that Halo is bigger than just being a shooter. It is
the shooter. It's the shooter that, no matter what other shooters are released, shooter fans will buy. Gt isn't just another racing game along with Forza, PGR, Burnout, DiRT, etc. It stands alone as part of the whole car scene, such that people who are not into games but are into cars know about GT and its influence.
I'm just trying to get the point across that GT5 pro is an indicator of interest in gt5.
It is an indicator, but it's an indicator without any calibration such that we can't make or predict measurements. It's like looking up at the sy and seeing dark clouds and predicting rain was going to fall. You couldn't say how much rain, nor even if it'd hail instead. It's like a Galileo thermometer where you can see the bulbs rising and dropping, but you don't know what density they are or what temperature they relate to.
I have two friends who are likely to get GT5 who haven't bought GT5P. If that's standard, then only 1:3 GT buyers have Prologue, meaning sales of 9 million. That'd be a stupid prediction to make though because I can't say for sure these two people are representative. I don't have enough information. Likewise we can't say "3 million sales of Prologue means less interest in GT" or increasing interest or stable interest or any particular degree of any interest at any pricepoint, other than 3 million people thought GT5P on an expensive PS3 was worth it for them!
