It looks like Android 4.4 Kit Kat and the Google Nexus 5 will definitely be happening sometime soon, definitely not today so possibly on 28 October 2013. It has been reported that some users in the U.S. are already seeing a Google Nexus 5 listed in the Play Store while others are still greeted with the good old Nexus 4. According to the listing, the 16GB Nexus 5 will retail at USD$349, along with the Nexus 7 and Nexus 10.
No further information have been given regarding the specs but according to recent rumors, the Nexus 5 should be equipped with a 4.95” 1080p display, powered by a 2.3GHz Snapdragon 800 processor, has LTE connectivity on board and up to 32GB of built-in storage. The link is unavailable for us of course, but if you know your way around that, do check out the Google Play Store to see for yourself.
