Why 802.11n still in draft?

Finally we're moving in to our new house after long construction and registration hang-ups. But I want to make sure our entire house including the court yard is Wi-Fi dead spot free. I am planning to replace my old wireless modem/router with MIMO (Multi-In, Multi-Out) one. Wi-Fi router with MIMO capability boosts network performance with up to 10x the speed and 10x the coverage of Wireless-G. It's a proven differentiation feature rather than a fancy marketing gimmick. However, I started shopping online to find a good deal; as usual now I'm suffering with Feature Fatigue, too many features and options to consider, sometimes it gives more confusion than containment.
I'm a member of IEEE standard body and also working in Telco xSP industry where lots of product developments are happening in Wi-Fi/Wi-Max domain. Next generation Wi-Fi (803.11n) was drafted long ago but facing continued hurdles to finally being ratified. 802.11n is the fourth major version of the wireless networking technology known as Wireless-Fidelity. Originally announced in January 2004, the technology has been adopted in its "draft" form by many vendors, but finalization and ratification is still nowhere close to being done.

802.11n promises to deliver a fivefold increase in speed, and double the range of 802.11g. Indeed in many cases it's already delivering something approximating that, as pre-standard kit has been available for almost a year. Netgreat RangeMax NEXT Wireless-N Routers & Gateways product series extends the possibilities of wireless home networking by providing a Steady-Stream approaching 300Mbps, and is compliant with draft 802.11n. This would give you the luxury to stream high-definition videos from your laptop to media center TV while you're making internet phone calls, downloading mp3s or torrents. There are many other providers including D-Link, Belkin, Linksys, Netgear are already competes in the 802.11n space although the standard is not ratified yet.

One of the big problems now involves is the patents. Apparently Commonwealth Scientific and Industrial Research Organisation (CSIRO) owns some patents that cross into 802.11n's world. And the CSIRO has not promised not to sue anyone who develops 802.11n technology. So the IEEE standards body, responsible for ratifying the protocol, waits and waits. Hoping something will happen.

This means that anyone who implements, or is implementing, 802.11n is at risk of being sued by CSIRO, and that the standard is very unlikely to be approved. Any equipment with draft 802.11n may already be infringing on CSIRO's patents, which could create a horrendous drama if CSIRO decides to sue.

Biggest concern is what would happen next. 802.11n shouldn't be the end of the line for Wi-Fi development. Will these problems cause development to end, or for vendors to start developing their own, incompatible technologies? I don't want my Linksys long range USB adapter to be incompatible with Netgear's NEXT router… who wants another HD DVD vs. Blu-ray war?
