TFK why are we still arguging nand pricing ? In January of 2010 Intel / micron announced 25nm nand with production ramping in qtr 2 of the year for 8GB dies they were able to decrease the chips needed on 34nm by half.

August of 2010 intel/micron announced 3bit 25nm flash nand which is about 20% smaller than the 25nm process above

While the jump to 25nm decreased the chips needed by half , the 3bit cell tech will allow them to fit 20% more chips on a wafer thus lowering costs further
They currently have 64/128 in production for mlc and 256/512 sampling. 256Gb is 32GB .
on the older process a 32GB flash card would need 8 nand chips. On 25nm its 4 on 18nm it will be less and on 12nm even less. Each time costs go down.
in the future smaller games may only need 1 nand chip for 8 gigs of data more than what the 360 has now.
During the next gen of consoles we should see all those process nodes (some before the next gen consoles most likely ) and am ovement to 450 wafters from the 300 ones now.
