AnandTech has a look at a couple of "draft" 802.11n WiFi routers:
We currently expect the differences to be resolved in time for a second draft to be completed this November with a letter ballot going out in January of 2007. If this is approved we can expect final ratification in late 2007 or early 2008 although we very well could see a Draft 3.0 in the spring if real progress is not made this winter. However, the products released that meet an approved Draft 2.0/3.0 specification are almost certain to be fully compliant with the final 802.11n amendment. Let's see how our first batch of Draft N products performs at this time.
