Given that the current model Xbox 360 can indeed be placed upright (although it can lead to disc scratching if the surface it’s placed on isn’t perfectly level and subject to being bumped into while playing a game or watching a DVD), it’s a given that some owners of the upcoming Xbox One will be looking to do the same with Microsoft’s new system.
However, according to this GameSpot UK article, a company representative says vertical orientation isn’t how the new console was designed. Of course, there will be a ton of hard-headed or space in that entertainment center challenged gamers who won’t follow the company’s “suggestions” at all or try out that standing position just once to “see if it works”, and you can never stop those folks from doing what they do.
On the other hand, I personally feel that there’s another, far sinister reason they don’t want you to stand that thing up… especially if you happen to do so and place that new, improved Kinect on the now top part of the system and power the thing on. To wit (actual test footage stolen from a Microsoft test facility):
