I was out in line for Black Friday last night and the amount of people buying PS4's was huge, way more than people buying XB1's, like 20 to 1. No offense to Xbox people play what they enjoy. I simply noticed BF sales was another big jump for PS4's in US so the problem probably isn't just EU launch alone!
Black Friday deals are set in place by the retailers so no this doesn't apply to PSN, that's not to say Sony doesn't have plans of their own, I however have not heard anything about it so I wouldn't expect it myself. :/
This is just my opinion, but I think post like this only indulge in what these horrible people hope to achieve by commitiing such horrible acts, they want to leave their shit stains on society and thus bequeath their legacy in human history. Articles and Shows that dive into their lives only solidify this for others out there who praise them or look to leave their own marks, we shouldn't remember these people, they should be treated like the trash they are.
