Next week is the Nokia World event, which is an event that will announce and unveil new devices. One of the devices that will probably come to surface, is the Nokia Sabre, a Windows Phone Mango handset, which will be considered a mid-range device. The price of the Nokia Sabre has not been made official, but it's expected to be in the 300-350 range.
As you can see in the photo above, the Nokia Sabre will come with three WP keys, the Windows, Search and Back keys. Two of the keys are visible in the above photo, but we assume the Windows key is hidden underneath the person's finger.
