Future-proofing: Should I get a motherboard with M.2 & SATA Express on a new build?

[Sparktown]

I've almost finished planning a new build (my first one). I already had a mobo picked out - the AsRock Fatal1ty H97 Performance (I'm not planning on OCing). Then I started reading about M.2 and SATA Express. For about $11 more I can get the AsRock Fatal1ty H97 Killer, which appears almost exactly the same except it also has a M.2 and a SATA Express connection.

I don't want to throw away money, but an extra $11 wouldn't break the bank. However, I already bought a Samsung 850 EVO SSD. I don't imagine needing another SSD for awhile, so this is strictly about future-proofing. In a few years, I might consider a M.2/SATA Express drive if the technology matures, prices are affordable and it gives a significant speed increase over normal SATA SSD.

The future of M.2 and SATA Express seems uncertain. Maybe their standards might even change and make the connections on the H97 Killer obsolete? I'm very interested to hear what people think the future holds. Is it worth paying a (relatively small) cost now to future-proof a new system? Thanks.

Personally, I don't see myself needing the extra bandwidth of the M2 or SATA Express busses (I have an 850 Pro, and it's just so damn fast), however, if you're planning on keeping your PC for a while, for $11 you might as well (just check if it's PCI-E M2, or SATA M2 it supports - SATA M2 shouldn't work out any faster than native SATA).

The Fatal1ty H97 Killer supports SATA3, PCIe and PCIe x4 M.2 SSDs.

Performance of M.2 PCIe x4 SSDs, like the Samsung SM953, already far surpasses the performance of any SATA-based SSD.
