The beauty of Bitcoin is that we don't have to trust Hearn or Gavin or anybody. We trust the code. We trust a valid argument, no matter who makes it. Core devs need to get their shit together toot sweet. If it takes a hard fork to make that happen, so be it.
they're all getting together for a talk-fest, kumbay-aaah session and maybe a group hug at the end before satisfying your demands for releasing a joint statement ... and then they'll delay some more and have another talk-fest in Hong Kong in December ... no panic, no rush, just some measured think-sessions by the thought leaders.
So far I haven't seen any leadership among these "thought leaders". A time frame for a joint statement about a time frame does not exactly instill confidence. Last time we really had an urgent problem (backwards compatibility), Gavin took the reins and it got handled. If we had a similar crises, who would have the street cred to pull that off now?
If Gox taught us anything it's that no news is bad news. Miners want higher transaction fees and they will end up with a bigger slice of a smaller pie if this continues. They can't win but they can make us all lose. By opposing a block size increase for whatever reason, they limit the value of the coins they sell and I as one of their main customers will shop elsewhere.
