XMR difficulty has gone up dramatically the last 3 weeks, are those FPGAs in play now?

Seems like a really gradual increase and nothing like a sudden introduction of a new mining machine. If i was to speculate anything i'd say the gradual increase would be a result of the GPU miners who shifted from mining ETH to XMR.

If anything, we should see XMR difficulty go down once they fork away from ASICs.
