I'm pretty sure intel's plan is to flood the market. Why else would they be developing hybrid cpu/fpgas (like APUs) or why would they bother to create the CCIX interconnect? They're definitely going to flood the market.
Well, not meaning to repeat the obvious, but it seems that not only does GPUHoarder have special insights into the private business relationships of Bitmain, NVIDIA and AMD, but you have them with INTEL !
Seriously, they won't be flooding the market with cheap UltraScale+ FPGAs if they flood the market with anything. Integrating some kind of FPGA functionality on an x86 die, ok. Serious enough to be useful for mining advantage, unlikely.
