IMFT got NAND down to 20nm with 3K - 5K write endurance. Hynix has plans to produce 15nm soon(unclear on endurance). Many thought getting NAND to it's current level would be impossible, the same could be said about hard drives. Write amplification isn't much of an issue with smart firmware. The new memory techs aren't market viable as we speak and it's questionable if first generation commercial devices featuring them will even be available within a few years and at what cost? Many of them also have drawbacks which hamper their viability or parallel the drawbacks of NAND. I still think a real replacement for NAND is probably a decade out at least.
