The gave you PSX and are busy with China, what more do you want bruh!?

yeah that's what I was saying.  What you're talking about used to happen worldwide where Xbox would normally win most weeks in November and December.  This gen it's only happening in NA while WW continues to be in PS4's favor.

They gave us all the PR we need, "Playstation 4 is the fastest selling console of all time."

Globaly or globaly in the USA?

I don´t think that title will hold after this december.

May be ir will catch again after year 4, when Wii started falling like a rock.

I have had access to Mercury Research Group pricing reports, and cannot post them here (nothing since late summer anyway due to my business structure), but can tell you this :

GDDR5 prices plummeted after the *coin mining rushes failed. They were already falling anyway. This is why you now see many 4GB GPUs slotting in at prices previously reserved for 2GB and 3GB GPUs. Also due to the mining craze, capacity for GDDR5 production increased massively from previous years. So the production facilities have to either be idled, or produce more for less $. I saw prices fall from ~$12/GB to ~$7/GB to ~$4/GB over a relatively short period of time.

This is the usual cycle with memory pricing anyway. Here are the stages relevant to your questions :

Stage 0 : Engineering samples are made after the design is more or less finalized, and sent to OEMs to test with their PCBs or other hardware on their ends. Basically a compatibility/testing/quality/performance measurement stage. VERY high price to get this done.

Stage 1 : First production for release in the market, the 'bleeding edge'era. DDR4 is still roughly in this stage. Production numbers are low, implementation is low, and price/GB remains high for awhile.

Stage 2 : Early mass production. Some major market actors have moved this memory into mass market items, and a lot is needed out there, so production increases. Price/GB is hugely lower than stage 1, but still moderately high. Last-gen memory still being produced in decent volume.

Stage 3 : Mainstread mass production. This memory type is now the de-facto standard for whatever, and pricing is incrediblycompetitive. There may be some price fixing on this due to just how cheap it gets. Cheapest stage for Price/GB. Think last year when you saw sometimes 8GB DDR3 kits for $30-$35 retail.

Stage 4 : Downhill of mass production. Combination of low margins and lowering demand overlaps when OEMs are moving some of their demand to a different standard, which results in manufacturers retooling for the new memory in some cases, idling production, looking at stockpiled inventory, and trying to cut a good balance. This is the current stage of DDR3. Pricing increases steadily.

Stage 5 : Basic EOL of mass production. Due to the stage 3/4 timeframes, enough manufacturers have achieved large inventories of these ram chips, which can be put onto various PCBs with ease, but demand for new memory types along with massive dropoff in demand for the old means production is largely shuttered on this kind (for purposes of this example at least). Pricing increases again fairly significantly.

So that is it. With DDR3, it's already passed the time that it is at its cheapest, and is now on track to steadily increase over time. DDR4 is rising steadily in high-end areas, but will truly make the leap to mass market next year, which will cause DDR4 prices to plummet, and DDR3 prices to rise sharply.

If you want an idea of how it ends, look at this (just purely using consumer-available parts as an example) : 

4GB DDR2-667 $119.99 http://www.crucial.com/usa/en/memory/ct51264aa667

4GB DDR3-1600 $39.99 http://www.crucial.com/usa/en/memory/ct51264ba160b

4GB DDR4-2133 $57.99 http://www.crucial.com/usa/en/memory-ddr4/ct4g4dfs8213

Over the next 6 months, watch the prices on DDR3 and DDR4 start to overlap and move in different directions. DDR3 will eventually be as insanely priced as that DDR2 stick up there, and DDR4 will become very cheap, then start ramping up all over again as the cycle repeats.

GDDR5 is a bit different than all of this. It's more specialized, but also lives in a similar cycle. Pricing is still falling on GDDR5, but eventually this will rise as well when it's no longer mainstream.

I don't think Sony really needs to say anything in regards to NPD!

Sorry, but this doesn't make sense if you don't look at the full picture. DDR3 modules are cheaper than GDDR5 ones, but this choice made MS put EDRAM on the CPU die, making a much bigger APU with higher loss ratios during litography and way more expensive to manufacture. PS4 is cheaper to manufacture. PS4 will also cut costs faster, because the price of GDDR5 memory will go down faster than the cost of manufacturing a big APU. Add to that the fact that DDR3 modules will actually get more expensive when DDR4 becomes the mainstream norm and we have a recipe for a disaster in cost reduction.

Sony profited more with the US$ 400 PS4 than MS with the US$ 500 X1. Kinect costs 75 bucks and the price went down 100, so MS probably sells it at a slight loss.

Sony will always be ahead of MS and Nintendo this gen in console sales. They have nothing to brag about because it's a given. MS fans are celebrating, which is great keep the party going, but Sony knows they're this gens Wii. However, Xbones price cut and their success might have them restructuring their ideas.

this gens wii would be great sales for 4 years then dropping like a rock. I'd imagine SOny are trying to be the PS2 of this gen with continued big sales for 10 years. 

You get the point, but gaming won't get that big again. It may have dropped like a rock but it still holds #1 of last gen, don't forget. Mobile gaming isn't only hurting Nintendo you know. It won't reach past 100M. I'm just saying, big profit, mass appeal, and tons of multi million sellers.
