Hm, I'm doubtful of this information, the fact that it only contains 2 worlds as a "special set" and focusses on two worlds that are already being built upon in EBs and BTs, it just seems unlikely.

Also, the fact that you said 11/21 (21st november?) seems too close for a special booster set to be released, without yet even being announced, they usually announce their new sets months and months in advance, but then again, FCE02 for Vanguard was only announced for november a few weeks ago, so it's possible.
