So you think you'll be able to at least recoup a portion of your cost before the fork?
I think I have lot of time with ETN

My friend is really excited to play with it, hope he can OC it a lot

If it's true FPGA it should be no problem to update, there are no big changes, Baikal would fix all these trust issues with firmware update also.
1. I doubt its FPGA. No comfirmed sources yet, all just rumors
2. Monero will fork twice a year. I doubt Baikal is willing to keep upgrading that often.
3. Even if it does, Monero devs hate ASICS with a passion. I am 100% sure if Baikal tries to update the devices regulary they will take more drastic measures. For instance something like x16r algo.
The bottom line is if the coin devs wan't to fuck up ASICs they can and manufacturers can't do anything about it. Thats why I am sticking to GPU mining. I can always mine something no matter what and I can addapt to any situation. Lesser gains but way lesser riscs.
