We decided to add certain clock buffers to improve noise-resistance and possibly increase frequency even further.
Sense most comments are pessimistic let me try to be optimistic by asking a question..
Is it possible that BFL is pushing their upper clock limit from 1 GHz to 1.5 GHz or even 2 GHz to squash the competition?
If that were the case, wouldn't they have just said so from the moment the delay was announced? Instead we get some odd-sounding statement about them adding a few more nines onto their 99.999% chance of success.
And that's saying nothing of the damage caused just by any delay whatsoever, regardless of its cause. Time is money in this game, more so than 'most anywhere else.
