...or US$399...if you will, why is that some benchmark to buy into..? Frustrating me to see many forum'ers kept claiming..next gen wont be a great leap...Sony won't want to lose money...Nintendo success with cheap Wii/DS paves the way it is meant to be....this is so restrictive....i want my consoles US$599....big box...250W TDP...big exhaust...big graphics...big computational... like so many people won't mind paying US$600+ for the latest phones...tablets...or even more with data plan...US$800++ and the phone will be worthless in 2 years.....you telling me the 4G radio is that expensive...? the processors these mobile devices are using..happens afaik in the past we refer to them as budget chips...the celerons and durons and atoms of the batch....
When...if...though unlikely..that Sony announce PS4, to again ...strike at US$599....you know those "pro" game sites will start making jokes about its price tag...Sony is doom! ..bloggers...forum'ers...will go viral about US$5-9-9 gifs and all...spreading the doom! ..this is so sad when you think about next gen...
Console are evolved toys, for most like me their marginal value is lower than the the one of a computers, slates, phones.
Then about how a manufacturer will price something is factor of BOM but more importantly which part of the public it wants to reach and so the match (by the top) the marginal value a game console has for the part of the market, for enthusiast like you it seems that +500$ is not a problem. For me 300 is a maximum as I can get way more useful device for the price (from PC to Phone) and I can't justify to my self spending as much in a gaming device.
So why the price is not going up with inflation? That's a good one. Pay check not going up fast enough, marginal value vs other electronic devices. And how it's achieved is even more interesting, lowered margins, modern form of slavery, currencies manipulations, low custom taxes on critical products (entertainment is critical go figure) and ultimately Moore law. But assuming Moore Law allow to decouple from inflation by it-self is a joke.
Subjective vs objective approach of the economy. You're going in the wrong direction primary materials are not what make the price of a product. The market/ Human give a price for a product then the rest adapt till it can basically, for now tricks and progress have CE devices to kind of decouple from inflation when this reach the end of the road the market/human will make new arbitration on what should be the value of CE devices then adapt price, replacement length, etc.
Back to our question is strategy after +7 years how much of your costumer do you want to transition to your new system fast ? 100% obviously won't happen. How much production constrained will you be at launch ? If you price your system to reach most of your user base you will be production constrained no matter what => Can price higher feeding a specific part of your user base. An interesting question is how much a manufacturers can deliver because it important to pricing. If you launch cheap you would want to greatly increase the reach of your product as a trade off. If you peak at 10 millions units a year... then it not a good idea to launch cheap as you might find 10 millions users that will agree on paying a premium.
To give a picture out of my ass if you launch a complete system (including fancy peripheral(s)) at 299$ you want to be able to produce at lot, think more than the number of Wii Nintendo produced in the first years. You're trying to maximize your impact of the market, ideally you would want to not be production limited at all.
Gaming is a big market, I believe that one could get more users per year to transition than most believe if your production capacity is not a bottleneck, price is lo, etc. Once again primary resources is not the most important part, if you're willing to let aside the premium a part of user base is willing to pay on volume you are not able to get higher anyway, you will make a system so mass production is not a problem if you see what I mean.
Ultimately what decides what the system embarks and at which price is humans not technological progress and considerations in insulation. Business decision trying to fill human needs.
