About 25,000 fpga cards can work on all algos http://zetheron.com/index.php/fpga-performance-profit/
Several thousand fpga cards already sold by this thread guys + many bought directly.
At this moment in public not have profitable firmware and as soon devs will released it - thousands of cards will start mining!
I think ROI will be 5-10 years.

Aside from the cost of the FPGA's the effects the on the network hashrate is also my biggest concern.
I've read whitefire990 take on this on his website.
"It is important to understand that based on the daily rewards that a coin offers, it can support a limited number of FPGAs before the FPGAs overwhelm the coin and the profits diminish, as all the miners split a fixed amount of available daily rewards. There is a simple method to calculate how many FPGAs a coin can handle before profits start to diminish. Using Monero as an example, we go to a common mining calculator like coincalculators.io, and find that currently Monero (Cryptonight-7) has a network hash rate of 457 MH/s. We cannot increase that hash rate by more than 50% before profits drop too sharply, so we could theoretically increase the hash rate by 457/2 = 228.5 MH/s. With each VU9P FPGA yielding about 22KH/s, then Monero could support 228,500,000 / 22,000 = 10,386 x VU9P FPGAs before profits drop significantly. There are other coins on the Cryptonight-7 algorithm which sum total to a supported 12,376 FPGAs."

So in theory if FPGA's don't dominate the network hashrates like ASICS have done the ROI should be reasonable. Lets just hope that how it works out practically
