Apparently the Bluetooth 3.0 has a problem that it consumes too much power so even though the specs have been available for quite some time, they haven't been rolled out. The Bluetooth Special Interest Group has said that the new version, Bluetooth 4.0, could be launching in the 4th quarter of this year with devices such as headsets, phones and PC’s all getting the technology.
The latest specification allows devices with smaller batteries to utilise Bluetooth. Previous versions of BT required that a device had at lease a AAA or larger capacity battery to function. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run.
As well as utilising less power, the device also has higher speed data transfer. Version 3.0 was launched last year although it kind of fell flat on it’s face due to the power requirements needed. Version 4.0 fixes those problems.
The new specification will carry the high-speed Wi-Fi feature introduced with Bluetooth 3.0. That allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.
Hopefully with the lower power requirements and the options to switch to 802.11 networks we should start seeing more devices using the Bluetooth specification.
However, Forrester Research analyst Charles Golvin believes the new standard nonetheless holds considerable appeal.
"These protocols are designed to be very efficient because they are delivering small bits of data," Golvin told PC World, adding that current technologies expended far too much energy to transmit data over short distances. “They'd be like pulling out a cannon to kill a mouse,” Golvin said.
Despite being certified nearly a year ago, the first Bluetooth 3.0+HS devices have yet to appear on the market.

Very interesting comments. May I know how you get the info about the concrete power consumption requirement? "Previous versions of BT required that a device had at lease a AAA or larger capacity battery to function. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run."
Besides I just saw from the internet that Samsung just released an android based phone with Bluetooth 3.0. I guess maybe you are too pessimistic about BT 3.0.
