but going ahead there might not be "small connector" SLI for future cards ._.

Yea, so currently no NVlink cables as far as I know.
They seems to be different pin density than normal PCI-e slots, and the micro chip on them might be for some conformation of "true" brigde.
(or just LED control)

So longer flexible NVlink cables might not be that possible :-(
