Bitstreams+miner or it didn't happen. :-)

The only thing that has been demonstrated thus far is that buying a VCU1525 for mining Keccak is a not a sane proposition vs. getting a 1080Ti for mining ethash.
I am still very hopeful that other algorithms such as CN7 will make this into a much more worthwhile endeavour.

Most importantly, however, I think the profitability measurement should be based on what can be achieved with an unmodified FPGA at 30C ambient temperature, rather than based on optimistic measurements with modifications that involve replacing PCB components.
