By the way, if you've all only been remotely watching the scaling debate from a distance, segwit2x appears to truly gaining enough traction to bring segwit activation to the fore.

The pools that signed the agreement just started signalling for it and it is taking off faster than any other scaling signalling. See:

Unlike the original proposal, it includes BIP91 meaning it is compatible with core's segwit now. The rapid adoption of segwit2x, which with the addition of BIP91 means that miner activated segwit is now likely on the horizon at last, and since there is overwhelming support for it and the associated 2MB hardfork in the future, that may also follow.
