Does someone have an estimate for when the next Great Plex Sale will occur?

There are many in the Eve Is Dead/Dying and This Will Be Closed threads here, but they are all opinions. If you go through all the posts on the matter (not just here, a lot of gaming sites has posted on this and reddit has some long threads too by now). You will find many links to various things, the only thing you can really tell for sure is neither PA nor CCP denies the sale is ongoing, and people like to spew a lot of wrong info fx the price originally paid for CCP (when people say 160, 200 and 425 you know at least 2 of them are wrong, they might all 3 be wrong, need more info to figure out which are wrong, and if its 2 or 3, but 2 definitely are wrong).

Suggest to start with https://insider-gaming.com/exclusive-pearl-abyss-issues-statement-on-ccp-games-sales-rumors/ linked in Eve News, Weather, and Sports June 22 '25 - #3 by John_Rochard for the very brief summery on what seems to be the actual known things right now. Assuming you trust them to not lie about having asked PA and CCP.
