The Nokia E71x isn’t a very old phone at all, but it’s about to get outdone by the business-class E72, seen here in a leaked promotional video. One of the most interesting things is the optical mouse instead of the clickable D-pad usually found in similar models.

Other upgrades include a five megapixel camera, a relocated headphone jack. That’s about all of the info we have. The YouTube video’s been pulled, but luckily IntoMobile snagged it quickly if you want to have a look.
