Certainly WiFi is still being improved, depending on which characteristic you deem to
be important. Gigabit Wifi ("WiGig") is only 12 - 24 months away, with one group
working on 1 Gbps and another working group working on 7 Gbps (look for 802.11ad) (see
http://www.engadget.com/2011/06/03/panasonic-shrinks-wigig-for-cellphones-sets-our-hearts-a-flutte/
for first silicon announced last week).
The kicker is that these use the 60GHz frequency band, which has high attenuation even
in air - the maximum range of WiGig is expected to be roughly 5 - 10 metres.
NICTA here in Australia has been a leader in this area.
Widespread streaming in the home should be fairly seamless using this gigabit-scale
link speed (compared to 802.11n which can achieve 40 - 60 Mbps half-duplex real world
file-transfer speeds), but only within the same room. For networking the kids
cubbyhouse out the back, 802.11n with slower speed but longer range, is still likely
to be the solution.
