They will get 4GB and they will accept it.

Typically, consoles manufacturers have favoured higher performance memory rather than more memory ...

I don't think that a system could be affordable with 8GB of high performance memory (and certainly not with 32GB of high performance memory), and I'm not sure if developers could get the kind of real world performance out of lower performance memory.

Essentially, I suspect Microsoft and Sony could get 8GB of DDR3 2000 (PC3 16000) memory, but I doubt they could afford that much of DDR3 2800 (PC3 22400) or GDDR5 memory.

I'm surprised by how developers are insisting on higher RAMs. Consoles are not designed to do multitasking like their PC counterparts, which makes 8 GB RAM's advantage least utilized on consoles. Instead a 4GB RAM(console's exclusive with higher bus frequency) would suffice more than enough for next gen gaming. Crytek better not be eulogizing higher memory requirements to utmost proportions, instead a little bit about what CPU/GPU next gen consoles use.

JayWood2010 said:   GAMING Crytek Exec Says Next-Gen Game Console Requires 8 GB RAM By Aki Libo-on Posted on December 26, 2012   Microsoft Xbox 360   | Wikipedia Crytek Chief Executive Cervat Yerli laid out his observations during an interview with gaming website Video Gamer. According to him, next-generation consoles will require more RAM—about 8 GB or more—for maximum performance. The exec added that console memory is “the single most important thing that is always going to be underbalanced.” Although he is referring to Xbox 360   andPlayStation 3, Yerli stated that the reason for the underbalanced console memory is the gaming system’s production stage. He then suggested that the purported Xbox 720 and PlayStation 4 may feature 8 GB RAM or more. Yerli even added that Sony and Microsoft could quadruple their respective console’s memory. That is if they can look for ways to cheapen its production cost. Although a 32 GB may sound far-fetched, the exec strongly believes that more memory is necessary for console makers to come up with a next-generation cutting-edge gaming system. New Sony PlayStation 3 | Sony Official Website Purported Release for Xbox 720 and PlayStation 4 Industry pundits are expecting that the so-called Xbox 720 and PlayStation 4 will be released late next year. However, a recent report from SemiAccurate states that the purported consoles are facing production issues. Thus, their release could be delayed to 2014. Also dubbed as Xbox Next, Microsoft’s rumored Xbox 720 used to carry the Project Kryptos moniker and reportedly comes with a developer test system chip called Oban. Earlier this year, it was reported on the website that the console’s processor was in the works. There were also about 10,000 initial orders of the Oban wafers being manufactured by IBM primarily. However, SemiAccurate also reported about a couple of problems in Microsoft, which could cause the production delay of their purported next-gen console. Asposted on the website last September: The chip, which is still referred to as “Oban”, is being run through multiple fabs in very high quantities, too high by more than an order of magnitude to simply be for dev kits…. Given the sheer number of wafers Microsoft contracted for, this seems to be both an anticipated problem, and one they have plans to work through. As for Sony’s PlayStation 4, the project is called Thebes, and it carries AMD CPU and GPU. Most likely it will be released in the spring of 2014, but it could be postponed until fall of the same year. However, these things remain as “speculations” until an official statement is released by each gaming system manufacturer.

All I'm gonna say is "called it in the other thread". 

8Gb RAM is something natural for next gen, I don't know why people here are crying because of something like this, all Sony consoles, for example, had their memory increased by 16 times, with PS4 won't be different.

PS1 - 2MB

PS2 - 32MB(16x 2MB)

PS3 - 512MB(16x 32MB)

PS4 - 8Gb(16x 0.5 Gb)

Yes, and that's been a problem. Look at the backlash SONY got/gets for not having some in-game features that the Xbox had like cross-game chat, custom soundtracks, etc. The complaints have died down since multi-tasking has improved and features have been implemented but many still complain about how slow the in-game xmb runs. Luckily the Vita didn't have this problem as it was built with multi-tasking in mind from the begining. 

Another example would be the WiiU. Before it launched, a lot of the talk on forums was just about how robust and fleshed out the in-game features would be. People really wanted some clarity on this. Ram was a big subject matter as that would be a good indicator of what to expect.

Going forward, fleshed out multi-tasking is somewhat expected. At 4GB, 1GB or less reserved for OS and it's features, I think SONY and MS's systems will be fine in this regard. 

Have you also noticed that Sony's consoles have been getting progressively more expensive to manufacture? The PS1 was sold for $300 and (probably) turned a profit, the PS2 was sold for $300 and rumoured to take a $100 loss, and the PS3 was sold for $600 and rumoured to have lost up to $300 per system at launch ...

8GB of high performance DDR3 memory is selling for $200 to $300 today, and 8GB of high performance GDDR5 memory would be more expensive than that. Certainly, you can get 8GB of low perfomance DDR3 memory for very little but pairing that up with a high performance CPU and GPU would be like creating a high performance car with a 3 speed transmission.

Don't you know that the cause of the loss was the blu-ray? each drive did cost $300-$350 for sony in 2006, if the BD cost the current $50 or less back in 2006, Sony would have launched the same PS3 with profit. BD is not a big deal anymore, as I said, it costs less than $50 nowadays.

Faster more optimized architecture is more important. Quality over quantity

It is possible that without the additional cost of the Blu-Ray player Sony could have launched the PS3 for $600 and broke even, but the system was still $300 more expensive to end users because of the escalating manufacturing cost associated with running a processing power arms race.

Sony's systems have gotten larger, ran hotter, and had higher manufacturing costs with each generation to produce the kind of processing power increase you're expecting. If they try to do it again, even without a new disc format the PS4 will be selling for $600 while taking huge losses again; after all, it would have 8GB of GDDR5 memory, a GPU from a $500 graphics card that uses 200 Watts of energy, and a gigantic custom CPU that uses 200 watts and is insanely expensive because its chip yields ar so low.
