Because it means they are late on their previous deadline, and it means that they once again cannot keep to their timelines.

People have called and asked if this is a new deadline and they reiterated it would be released before or on the 21st. Much like the latest RE, there was verbal confirmation of a date. I sure as heck hoping they stick to the 21st deadline.

Can I wait another 9 measly days if it is not out on the 21st? Yes of course. But it is the principal of the thing. Keep to your word. It is one thing that they are on the 11th hour of their latest deadline.
