one would expect that with the smaller NAND. this could be why samsung is mulling not building that NAND plant? this is also why you didn't see OCZ BF3 using 20NM nand like the liar had said it would be.
Samsung will need the 10 NAND plant which is slated to be completed in 2015. They will need to compete against INTC/MU, who are skipping 10 NAND and will produce 8 NAND instead. INTC/MU 8 NAND should be ready earlier than expected in 2015 as well.
