I'm sure many are heartbroken with the news, I'm one of them. That doesn't mean NGFF is a failure or will never live up to our expectations.
On the contrary, bringing DEVSLP to ultrabooks and notebooks is a big step in increasing battery life. New cache modules also reduce wear of mechanical hard drives. At the same time, this is a stepping-stone used to move storage in a new, exciting direction.
One step at a time, all the way to 1,800 MB/s and beyond. Following NGFF PCIe is another new technology called SATA Express. If I were to guess, SATA Express is the reason why NGFF will ramp up slowly. We all have x4 lane PCIe on our motherboards and we look at those slots and wonder how to populate them.
I don't think we will need to wait for 2014 to make use of the extra four lanes, but as of Computex 2013 we are not there yet. Flash Memory Summit 2013 should be exciting and by CES 2014 the next push will come getting us closer to where we all want to be.
