Neurus_Ex: Huh, that's weird.
I use Playnite and it has shown me that there's a (new) Quake Enhanced on my account. Going there it shows an actual page in Galaxy.
Maybe, finally, after a year and a bit, Bethesda has decided to give us the darned update?
EDIT: I've installed it. Will update in a bit.
EDIT2: Looks like this is it, boys. Let's wait for an official announcement, but it looks like its finally here!
EDIT3: The Galaxy page does not show achievements, nor the "SuccessStory" plugin for Playnite, so it looks like we are getting a discount update, or it is not 100% ready? ...but there's achievements inside of the game itself.
EDIT4: The store's page description is also updated to quake enhanced's. Although not the game's name.
EDIT5: There's now two diferent items on the library (See the other attached capture). I'm wondering if they've replaced altogether the original Quake version (and new purchases don't have it) or if they've gone with splitting the game into two different items. Looking at other games (Baldur's Gate), it could seem they've nuked the original version.
EDIT6: Trying to connect to my Bethesda.net account from the game returns an error at the moment.
Reading the store page, it looks like if you buy Quake, it puts them both in your library bundle-style, so use whichever you like. Makes sense since Steam did similar, offering up both versions when you buy it.
