It seems like these new E3 can be upgraded once ETH will fork and still mine it. I heard this from "insiders"..
Can you provide more information? Is it using and FPGA versus ASIC? Is it really GPU cores inside?
How exactly could they upgrade it after the fact?
I've heard this rumor as well. FGPA + GPU cores is what's rumored, which (given the size) may be the case. If it's just a bunch of DDR3, then chances are it'll be worthless after a decision is made to brick them on Friday (because - let's be real, it will fork).
Problem is, FPGAs aren't always cheap. So unless Shitmain came up with something proprietary, I would consider this to be a rumor.
