Xbox One S was sold for 174 € this week at Saturn. Black Friday isn't really a thing here. People slowly begin to adopt it for some reason, but it hasn't really caught on just yet. There are a few deals, but the people don't rush out like crazy like americans do it (or at least that's what I'm being told, never been to the US on black friday =P)
Also, Sony themselves did nothing at all. Media Markt lowered the price to 196 € (amazon followed, like they always do), but they did that before. It's just that the dealers are more focused on PS4, because the Xbox is pretty much dead in europe apart from the UK.
I don't think Microsoft gave up though. I mean they even didn't give up in Japan for crying out loud.
