That's only a slip if you haven't been playing very close attention to Josh's statements. Josh makes a lot of predictions based on terms he refuses to define. In particular, Josh's meanings for "pre-order" and "back order" are never defined anywhere. He intends for you to assume they mean what you think they would mean. But there is strong evidence that this is not the case. Not the least that he refuses to define the terms even when cornered. That should be a red flag that it's a key weasel word.

IMHO when BFL says "pre-orders" or "back orders" you must assume it refers *only* to orders placed *before* April 1, 2013.

I say this because when Josh initially and loudly announced the chip credit program it was for "all pre-orders". But under the hood in the fine print it excluded April 1 and later orders. When called out on that Josh later edited his post to make it more forthright.

Now, please do note, that "With the current order book up to today, I expect it to be filled by the end of September" does not actually define "it" as the orders in the order book "up to today". The antecedent for "it" in that sentence is not properly defined (even when you view the entire post). The intuitive understanding for "it" when reading the post is the back orders. So what that sentence actually says is:

"With [reference to] the current order book [which includes all cancellations/refunds] up to today, I expect [the 'back orders'] to be filled by the end of September"

This does not say that all the orders through today are back orders, etc.

Anyway, this is just an example of how you think you know what Josh is saying, but he is never actually saying anything. He's quite skilled at that. So you can list thousands of his quotes and none of them actually say anything substantive at all.

Josh's communications are carefully crafted and deliberate line noise and you're a fool to interpolate meaning where meaning has been excised.
