Here is my latest bit of info:
I have a friend that I go to church with that is a
Disney Travel Agent (I wanted to talk to her yesterday but she was out of town). I just sent her a FB message asking if she had any insight on
free dining since we are hoping to book for September. I am quoting what she told me:
"We know that Free dining is coming for September and rumor has it that it will be available next Monday. I am sure that is why my schedule includes OT for next week

"
I then ask her if she knows anything about whether Disney Visa holders will get advanced notice.
"We normally get that information the morning that they offer the advanced booking and sometime we hear it from our customers before we hear it from our department leads. LOL"
Not sure if this is anything more than what Black has shared but the overtime comment is another great sign that Black is spot on again!!!
