Will WiFi 802.11ae Kill 802.11ac?

The wireless industry is currently pushing to finalize the new WiFi 802.11 ac format, potentially able to deliver up to 1.3 GBits/s. Some manufacturers, such as Buffalo and Netgear already offer products supporting this non-finalized format, based on the draft version.
However, it does not seem as easy as for the 802.11n format. Indeed, at that time, there was only on new format to be finalized, and several computers and WiFi routers and stations have been released with the draft version of the 802.11n format. A simple firmware update was then applied when the 802.11n final version was released couple of months later. Today, manufacturers are pushing to bring something new on the market, and actively supporting the 802.11ac format, however, the IEEE would rather like to promote another version, 802.11ae. While the latter is similar to the 802.11ac, it can make use of three bandwidths. In addition to 2.4 and 5 GHz common to both format, the 802.11ae can access the 3.7 GHz frequency, offering a good compromise between the high-range of 2.4 GHz and the high data speed transfer in low range of the 5 GHz.
so, this time it will not be possible to turn a 802.11ac wireless station into a 802.11ae station with only a firmware update. The difference is based on hardware, and if the IEEE 802.11ae is finally approved at teh end of the year as expected, products based on 802.11ac might have a very short lifetime. so, this is going to be a fight between the manufacturers on one side and the IEEE and customers on the other side, willing to have a simple and standardized format.
