Last Thursday saw the IEEE approve draft 1.0 of 802.11n. Competing groups of vendors have been struggling over the direction of 802.11n for some time, but a group of chip makers, including Atheros, Broadcom, Intel, and Marvell pushed through a near unanimous voted for the draft.

[...] the proposal will now be sent out for balloting among 802.11 Working
Group members for a 40-day period. Ballots will vote up or down on
accepting this draft, and will bring back comments and requests for
changes. In the May meeting, those changes will be discussed, and some
will be adopted and others not. If all goes well, a re-ballot will
happen following a similar course. In July, a final draft could win the
day, which would then go on to a group of experts at a higher IEEE
level who typically approve drafts—by the time they’ve reached this
point, most technical and harmonization issues across 802 (networks)
and 802.11 (wireless networks) have been settled.

Meanwhile, manufacturers will probably start firing up the
silicon ovens. McFarland said that Atheros was already in sampling, and
it was very encouraging that “In getting to this 1.0 draft very few
technical changes needed to be made.” There is a very low risk, he
said, of significant changes being made before a final draft is
accepted that would require changes in silicon.

If you're looking for high bandwidth wireless, you may not have long to wait. Of course, the only application I can really think of that needs this kind of bandwidth is something like transmitting mobile x-ray or ultrasound images back to radiology. I'd hate to see too much good hospital bandwidth sucked up diagnostic imaging.
