Ah yes, I forgot about the mandatory signaling period.
Still, if miners keep ignoring BIP110 they may be in for a rude surprise in September: a sudden, completely avoidable loss of income from BIP110...
I doubt it would represent a significant loss, and in fact I suspect that adopting BIP110 would harm the value of bitcoin more than losing these people would. But without fork futures markets --which I'm very much in favour of!-- it's anyone's guess unless and until there actually is a split.
(That's another argument for a URSF btw, it would enable a very well defined fork futures market.)
