Bluetooth Low Energy will be readily accepted. Most the BT chipset manufacturers is starting to sell dual mode chipsets which includes the LE standard. And it is just a matter of time before all sort of BT single mode devices (running only Bluetooth LE) appears in market. Regarding IMEC's wireless ban chip, it is not very difficult to build a wireless system which consumes lower power than BT. But its performance in the presence of multipath, multiple nodes, multiple interference sources degrades very fast. so will have to wait and see practical, real time performance of these devices.

Rick, Don't forget that there are several successful "ultra low power" proprietary RF technologies on the market with lower power consumption that Bluetooth and ZigBee (although admittedly not with power consumptions as low as that reported by IMEC). Bluetooth and ZigBee trade some power efficiency for interoperability. Bluetooth low energy will have power consumption much lower than "classic" Bluetooth (exact savings depend on the application) but will also feature interoperability. That will probably be compelling enough to see rapid adoption.
