As you say, the next storm of November is going to be a lot more serious than that of Bitcoin Cash. Personally, I still feel a lot of things can happen - either party can still change their mind for the common good, and a fork may yet be avoided or may be agreed upon by both.
I'm actually torn on this one in terms of game theory:
The natural assumption is that 2x is a bigger deal than BitcoinCash in terms of potential drama, but it's possible that the BitcoinCash split has actually taken some of the wind out of 2x's sails. If you consider that BitcoinCash will be taking a proportion of the hashpower and economic support that otherwise could have contributed to the 2x chain, then it stands to reason that November's 2x split could likely be diminished or weakened as a result. In a sense, it's better to have two infighting opponents squabbling amongst themselves than a single, organised and regimented opponent with their primary focus on you. If it's purely a power-play based on strength in numbers, those supporting SegWit-only should be happy that their enemy isn't presenting a united front.
However, it may not be a power-play at all. BitcoinCash could be seen as a kind of bartering leverage. If you make people realise that there is a more extreme stance that could be taken (BitcoinCash), then the middleground (2x) may cause compromise to appear more temping by comparison and could conceivably gain support as a result. It's really difficult to tell if those miners currently mining up-to-8mb blocks are doing it as a fallback because they genuinely believe it's the right course of action and the split is worth the risk, or if it's simply a sign of intent to make 2x seem more appealing by comparison and to strengthen their negotiating standpoint by presenting a more extreme alternative.
It'll be fascinating to watch it play out. I'm just gonna hodl everything to be on the safe side and consider my options once the aftermath is clear.
