Questions :
1 : Have Amd "fine tuned" the chips already so that the headroom for overclocking is lower on the 1800x models (not counting the luck factor) than the lower 1700 models? My impression is that both 1700 and 1700x might in fact have the potential to achieve the same clocks as 1800x. Or are we probably just seeing a bit of inconsistency in the bios and motherboards partners that might be fixed in the future giving perhaps better OC headroom?
AMD qualifies chips. We choose the best samples to be the 1800X, because it has to run at the highest clocks.
Does that mean a 1700 or 1700X can't run at those same clocks? Not at all, they might run very well at higher clocks! But they might need a bit more voltage and a bit more cooling to do so...
This doesn't have much to do with the BIOS, unless we're talking about memory settings and stability to support the CPU's overclock. And that is improving quickly with each revision.

2 : Any date for the next revision of Ryzen?Like Late 2017 or early 2018?
No dates, sorry. All I can tell you is that Ryzen 3 is coming in the 2nd half of 2017.
