FRONTPAGE G.Skill Officially Announces Ripjaws 4 Series DDR4 Memory Kits

Wonder how much tweak ability is there though. 3200 @ cl 16 isn't a slouch, imagine if you can drop it to 12

Imagine how much a 3200 MHz kit will cost 
You get benefits (in gaming) up to around 2133MHz unless you are using the iGPU of either Intel or AMD as they use system ram for vram so the faster it is, the faster your iGPU is as well.
Its simply a natural progression.
Just a side note on some of the timings/speed relationship here...
You can work out RAM access time this way: ( CL / Frequency ) * 1000.
CL16 / 3200 MHz * 1K = 5ns
15 / 3200 * 1K = 4.68ns
8 / 1600 * 1000 = 5ns
Though it should be obvious that the 3200MHz has more bandwidth.
Its simply a natural progression.
On LN2 maybe...http://www.jagatreview.com/2013/06/...vengeance-pro-3200-mhz-cl11-di-computex-2013/

You're comparing architectures here, assumptions like that won't apply.
The reason 1600MHz DDR3 was the sweet spot for so long was due to the speed/timing/cost ratios.
There will be a new sweet spot for DDR4.
It's like saying "This processor from 5 years ago was best, so this must be the best new one"

the old addage for 1600 MHz sweet spot was based on gaming benchmarks... (like Crysis and Metro 2033, not 3dMark or Heaven)
you could see a noticeable framerate difference going from 1333 to 1600, and then almost no difference jumping from 1600 to 1833. (i'm saying the addage was based on benchmarks, not the technical reasons for WHY benchmarks showed what they showed) and since 1833 was more expensive for ZERO to ONE frame rate increase, it didn't make sense to buy faster RAM unless you were competing for benchmark high scores.
nowadays, you can see noticeable differences jumping from 1600 to 1833, and in a few new titles, maybe even a difference jumping all the way up to 2133 from 1833.

From what I'm seeing so far, DDR4 kits will start at 2133 MHz and go up from there. Lower MHz kits should run at 1.2V and the higher speed stuff at 1.35V. Once DDR4 has been out for a while, I wouldn't be surprised if manufacturers start tossing out kits with better timings, we'll have to wait and see I guess.

Whelp. Time to looking around for 16-32gb 2133 set of ddr3 before all the good stuff disappears.

Not really that loose in terms of access time....
