The first hurdle to overcome is reaching 80% signalling of BIP91.
BIP91 has a good chance of being locked in this lock-in period already, and if not once Slush signals it should be more or less a certainty for next lock-in period.
I don't like all the FUD and conspiracy theories about why miners won't actually follow through with SegWit.
Yep I agree! Back up to 80.5% and BIP91 is projected to lock in during this lock-in-period, just 80 more blocks to go at this percentage or above and we're all good!
