Won't have a significant effect, doesn't take any longer to rewrite the program for a FPGA than it does for a CPU or a GPU.
In fact, the only "drop" will be from miners that don't get updated in time for the fork I'm CERTAIN.
I believe the changes to the algo are supposed to target the differences in architecture directly and cause massive slowdowns on FPGAs
We've seen this song and dance before - the whole point to a FPGA is that it can be reconfigured, so pointing at "the difference in architecture" is a meaningless statement.
I don't see them being ABLE to keep FPGA's at low performance for long it at all since a FPGA is MORE configurable than any GPU.
The actual devs explain it much better:

New ASICs will also be many times slower because of the nature of these changes.

Well, that depends on ASIC implementation. We don't know for sure how their internals work. But according to a lot of scientific papers about hardware implementations of division and square root - yes, looks like 16x times slower."

So practically & effectively this makes FPGAs 4x slower, making them much worse in terms of $/hash (see Xilinx FPGA, 22 kH/s CN7 for 4-5k$) than GPUs and ASICs 16x slower still being better than GPUs in terms of production cost/hash but they'll be useless within a couple months and not break even.
So this makes GPUs & CPUs the best thing to mine with, if Monero keeps the strict 6 months fork schedule.
Is this correct?

Yes, it's correct. At least 4 times slowdown compared to Cryptonight v1 for all kinds of ASIC/FPGA."
so even if asics are made they will be 16x slower
and fpga's once programmed will be 4x slower
these are the actual developers words not mine
So if they are correct
monero should have legs here it could be worth a buy and hold or at least mine and hold.
