He is right though...You say that like he was talking nonsense. He was perfeclty clear, you came into a thread specifically about the PS4 and started complaining about things that have nothing to do with what he was talking about. You seem to have mistook this for a PS4 vs. Xbox One console warz thread, it's not.

Lack of Dlna and MP3 won't harm sales considerably, but they might knock the top off the potential holiday peak. Harm considerably means either sales falling to the level of the competition, or ceding sales to the competition such that they sell much higher and closer to PS4 than expected. I don't expect either of these things to happen because of a lack of DLNA or MP3. It may happen for other reasons though.

Fair enough, I should say might harm sales considerably, but their is no evidence to suggest it won't have a sufficient effect. And its not just lack of DLNA or MP3, those or just examples, there are many things that Sony said the PS4 would be able to do that it hasn't yet. Concrete measurable things, not ephemeral unrealistic statements that like PS4 would be able to power your refrigerator or car.

Quanity = Quanity Supplied.  In otherwords, the ability of Sony to supply retailers consoles is Quanity.  Supply is the willingness of either the manufacturer or the retailer to supply an item at a paricular price.    Likewise, Demand in the above curve is the willingness of buyers to buy an item at a particular price level.

The Equilibrium point is where buyers will buy at the price level, and manufacturers are willing to sell at that price level.

If there is a shortage in Quanitity supplied, then the Supply curve moves inward, and the Equilibrium price increases.  If there overage in Quanity supplied, then the Supply curve moves outward, and the Equilibrium price decreases. 

If there was a true shortage, the price for the PS4 would increase because demand would outstrip supply, retailers would see an opportunity and increase the price.  

You're absolutely right, Economics does explain this.  However, I'm not sure it's saying what you think it is. 

Then again, maybe you're right.  I just passed my Macro Economics class with a 4.0 as the top student in my class.  My professer repeatedly letting me know that "If your classmates ever knew how many points you accumulated, they'd kick you in the shins.", but I could be wrong.  You never know.  I mean, my text book was written by the former Chairmen of the Federal Reserve, and not Wikipedia.  So...you have that going for you. 

You're only partially right, in that typically increased demand vs supply will increase prices. But the catch is that this only items with prices that are dynamic adjust to the market. Console are fairly static in price, dropping relatively few times comparitevely. Supply and demand does occur on resale sites like ebay and amazon, but the very second a retailer raises thier price because of supply issues, it will be undersold by every other vender.

Also FYI, the econ you study in school and the econ that drives the real world aren't exactly identical ;O

For example, regardless of avaliability, from last year to launch the official price of the PS4 was 400$, meanwhile the the PS4 on ebay could be found any where from 500 dollars to 800 because of resellers.

Agree with most of the points other than the racecar. The PS4 has 2 whole cores and 3GB of RAM unusable for gaming.

Its a goddammed metaphor!

Lol, but my point was, a racecar has everything and I mean everything taken out, including things like air-conditioning, safety features, seats, etc.

The PS4 dedicates more resources towards non-gaming elements than the PS3 did in proportion. I would say older, dedicated consoles like the PS2/PS1 were like racecars in terms of dedicating 99% of resources to gaming, but the PS4 ain't close, even when compared to the One, which supposedly uses a comparable amount of resources as the PS4.

Hence my "other reasons" caveat.

While I'm not going to argue the theory as I have no formal education in macro economics, I will say I don't think that bit about retailers bumping prices really applies here. I say that because for the most part retailers adhere to the MSRP set by the manufacturer even if supply is low compared to the demand. I'm sure you could name a plethora of reasons why that might be the case but my gut feeling is one of simply remaining consistent as to not confuse customers and to be sure they remain competitive.

Also, I think that most people either have or know someone who is exceptional at something or has an exceptional talent. It's great, but not really all that impressive. The real trick for someone with an exceptional talent is to be able to use that talent when it's appropriate without being a dick about it. You could have easily given your expertise and even mentioned your credentials without needing to toot your own horn or put anyone down.
