No. Just like the Xbox 360 and the Playstation 3 when they launched, developers loved it, but guess what? That memory in both systems became a pain in the ass a year or two after the consoles launched, that memory bandwidth and amount became a real limiter and quickly.
Developers started to ditch the 1080P resolution for 720P and some games wen't even lower than that so that they could improve image quality in other areas.
Why can't you understand this, I'll never know, but the same thing is going to happen again because Sony wen't with lower-end (relative to the PC) hardware this time around and Microsoft probably will too.

Also, games aren't just resolutions and textures.

As for the PC memory bandwidth, again you are completely wrong.
You are basing those numbers on DDR3 1600mhz memory, the PC supports many different speeds and latencies.
Grab some 2133mhz memory modules and whack them into Quad Channel, suddenly you will have more memory bandwidth available.

Remember: Bandwidth = Real clock rate x Bits transferred per clock cycle / 8
I.E. 1866 x 256 / 8 = 59.712GB/s.
If I were to get DDR3 2133mhz memory modules that would jump up to 68.256GB/s.

You can go even farther than that and get some DDR3 2400mhz or even 2800mhz memory modules which would put it at 76.8GB/s and 89.6GB/s respectively, certainly a massive jump from that 10GB/s or 20GB/s you stated before.

Again, people seem to think the Cell can do more than it can do.
Remember, Sony is going with a Netbook/Tablet class processor in the Playstation 4, think about that for a moment. Like spend 5-10 minuits on that point alone.
Then you need to realise that Netbook/Tablet class processor is several multiples faster than the Cell. Think again on that point for another 5-10 minuits.
Then come to the conclusion that the Cell is woefully inadequate, otherwise Sony would have dropped one into the PS4 if it was indeed the be-all end-all processor.
It's a cost sensitive processor to go into a cost sensitive product, it's not a high-performance piece of hardware, better than the Xbox? Sure. Better than your phone? Maybe and if it is, not for long.

1) Again your are wrong about memory bandwidth or you don't know what you are talking.

2) No. The CPU have a limit in bus width for memory... so you did overclock to reach there bandwidth... if you put a DDR3 2800Mhz in a Sandy Bridge-EP it will run in 51.2GB/s until you did over in the base clock in CPU. And quad-channel only exist in this processor in Desktop market... SIGLE and DUAL-CHANNEL are the default and used for more than 99% or the Desktops PCs... quad-channel is just userful in Servers.

3) Cell can do a lot of things... it is not a CPU... it is powerful in FLOPS than any other CPU in the market... so it is good for graphics tasks even better than a lot of low GPU.
