Should I wait for NVMe based PCIx storage for a new laptop?

[carnifexor]

I have been waiting on replacing my aging M14x r1, which I've replaced the Samsung 830 with an 840 Pro, until NVMe controller PCIx based storage becomes available in the retail world for pc's and laptops. It's currently available in the commercial world and Samsung does have a model available for it X1715 I know the architecture and speed potential for the storage controller type and architecture will double or quadruple (or more) current SSD speeds. I'm curious what other's thoughts are as to when we may see this in high end laptops?

Samsung has an XS1715 to illustrate as an example - link goes to a press-release: Samsung Unveils New Solid State Drives at its Annual SSD Global Summit | Samsung Semiconductor Globa.

My guess is EOY 2015. Would it be worth the wait or move to a generation in between? Not sure how fast this might reach consumer level.

SSDs are so fast already that unless you benchmark or have very peculiar file transfers you won't see the difference between a modern Sata III SSD and the new PCI ones.

In technology you should buy when you need. Otherwise you will be waiting then for DDR4, then Pascal and so on.
