By the way you don't plug speakers into sockets. Dont really know what they could be for though or if they're the right kind for lighting. This is really scraping the barrel for news.Could it be plugs for speakers
Or scarefest lighting?
A screen of some sort seems most likely like a TV or dot matrix display.Could it be a Samsung OLED 52'' 4K TV?
On a serious note it's nice that they are teasing this on-site more than a few banners.
Oh here is the pictures of the plug and stand, definitely looks like a telly will go there.
