Who said anything about end of Sept? As far as I know they said the BFS is/will be on time as per their last NR before the end of summer which is officially Sept 21. If it was going to be delayed past this date they would of said so in the last NR with some explanations/excuses but they reaffirmed that everything was on schedule. I think you may erroneously be assuming another delay from their statement when they said it would be out in Sept which I interpret as between now and Sept 21. In other words, we are on time and no change from previous NRs which repeatedly stated late summer.

I agree with Prospekt. The language doesn't give us a specific date. 2 weeks away and you think you'd be able to give a specific date or at least week not a whole month. The language isn't as strong with "September" and when you consider all of September opposed to "Late Summer" having about a week of difference (assuming the last day of each) - it's a bit of a delay.

All in all, people have been holding for a year or two and some even more than that, so a week is hardly going to make a difference but it does get frustrating.
