ASIC for Scrypt is a long ways off, and Scrypt is more resistant to ASICs anyway so we'll see.
If you can do scrypt with an FPGA efficient you can do the same with ASICs. It's only a question of the minimal volume you have to produce/sell.
Unfortunately this is true. You should keep asic on the table even if its cost prohibitive you would want to plan for 2 years away.
Definitely. In the progression of things FPGA is just the next logical step for Scrypt as GPUs get cost prohibitive with the growth of the whole network. ASIC Scrypt will come someday but will probably be a little while yet as FPGAs are just hitting the table, as they once did for SHA machines. Or maybe by then something better will come along, who knows

And as id like to say to both your self and jasinlee Im not against FPGA , not at all , its the potential to centralize that is the problem, if the multiple goes way out the window, the producers will mine with thier own device , this is a net monopoly effect also a centralization , then the market with have a concurrent effect , it will snap back at you , so i'm telling people to be careful, ASIC
will be the downfall of Bitcoin , you , and they just haven't perhaps realized it yet , (i suspect some of the smarter guys have)
what the market will do is find a novel way that an FPGA can't be reconfigured in an easy manner to adjust to , i don't decide this the market does, as i said open source C++ will evolve much quicker than FPGA and ASIC, so be aware of the risks, although i notice Jasinlee mining with his already, but thats not a net negative you guys just should be aware.
i will definitely order one based on the cost # power ratio - but just be aware that if and when the market feels that the equation needs a balance , kiss it goodbye. if they spread far and wide at a market price then that may delay this effect, but that whole profit motive tends to work against you there, irrational exuberance and the rest.
As you may have read already, we do not plan on distributing massive amount of fpgas and we will in the end offer our design in open source. And per laseeks recommendation and our spitballing we decided it would be best to have a hard limit to how many we carry at any given time. I agree the danger of a 51% (even if we were only solo mining) is possible and should be avoided at all cost.
