I totally get the "extra info and perks for backers" thing.
What I don't get is Peter's refusal to share at least *some* updates with the general public. There are a bunch of lurkers out there (I'm one) who are hoping this bike will succeed, but are taking a wait-and-see approach. Pretty much the only updates we get are the occasional items "leaked" here. With all the delays and almost no info made public in the last several months, how many of us have written it off in favor of other bikes?
