Considering the nature of Heroes, we do not have anyone with the time or resources to dedicate themselves to the upkeep of data that's being constantly added to the game that other sites (such as Gamepress, Gamepedia, etc.) have. So if you do need up-to-date Heroes info, you can visit one of the many other places such as the two I mentioned. But you probably knew that already. I will talk with Vincent about removing certain data that requires constant editing/updating and perhaps just turning the page into a more general overview type of thing, unless he is willing to find people he knows and trusts who will keep the pages relevant and up to date.
As for the Three Houses information, I haven't heard anything from Vincent regarding it yet but then again it's only been a day. It ultimately depends on his schedule since I'm sure he is more than capable of doing this stuff himself, and/or whether or not he is willing to give more people access to the main site.
I would say "next week," as @Captain Karnage stated, is a bit ambitious; I don't want us making promises only to leave people hanging. But for sure, knowing Vincent, the gears will start moving sooner than later if he has time to spare. All I can really say is thanks for being patient and I hope you don't mind waiting a bit longer.
