Yes you read that right, these domain names do exist but Xbox720.com and Playstation4.com though isn’t exactly what you think they’d be. If you clicked on the links, you can see that they redirect you to other sites.
According to Fusible, Xbox720.com used to redirect to the US Playstation website but the domain owner is taking advantage of the rising attention to redirect it to his own blog; a tech-news aggregation site.
The owner of the website is reported to be Jeremiah Germany according to Fusible. He replied to an email of theirs stating that he is indeed the owner and mentions that Microsoft hasn’t approached him about the site yet.
Playstation4.com redirects to a PlayStation news and cheat site.
