Pericles has been a Collector since yesterday but when you read the comic coming out on February 6th… then you’ll realize just how mythic our Patriarch really is…
From today, Pericles will no longer be available on the Market, and will only be in CR packs until Friday! Back on the Market over the whole weekend, Pericles will move up to Mythic status on Monday, February 4th and all will be revealed about his final sequence in “The Escape” Comic, available from Wednesday, February 6th!
-> make (previously unknown or secret information) known to others
So yeah, you're right. If there's nothing more to "reveal" besides how he "deceased", they basically killed an important (if not the only interesting) inducement to buy the comic.
