When FPGA mining really takes off and various mining solutions will be available from an assortment of manufacturers, should we expect an increase in price due to demand? Seeing how the GPU market wasn't affected by bitcoin mining, I'd hazzard a no, but still...
Not a precise guesstimate "really takes off", but I don't think mining will ever come close to the kind of market that some FPGAs are designed for,
like consumer markets or large markets like network switches, etc. I agree, don't think prices will change due to BTC mining.
