in short: too early to tell. be patient.
to explain
ethereum was not a consensus vote. it was an intentional split. as proven by " --oppose-dao-fork" mechanism that literally bans each side from orphaning off(consensus) each others chain,
if --oppose-dao-fork was never used, orphans(consensus) would have taken care of the minority to leave only a majority chain
i dont think we should be using ethereums tactic as a dirct comparison to what has been proposed by any bitcoin dev. but should be used as an
example of consequence/warning of proposing such stupid split idea's (again bitcoin dev proposals are not about splits)
bitcoin wants to stick to a consensus (either code required or social pretence) to ensure there is only one chain, chosen by the majority.
lastly miners dont/wont jump the gun soon unless they see good acceptance by users.
EG knowing a payment gateway can validate the segwit transaction, so that miners/pools can spend their funds to pay for electricity and wages.
which unlike ethereum who split before even seeing if exchanges would accept the split. which has caused loses.
inshort miners wont flag their desire for segwit unless they know merchants and exchanges will accept and be able to validate segwit tx's
so as i and Velkro said. be patient its not going to happen until merchants review and accept the code. and miners see their favourite exchanges/services accepting the code to know they can spend funds.
