What happened to Low-Power and High Speed Bluetooth?

It has been very quiet at the Bluetooth front for over a year now. The last time I heard of Bluetooth in the press was when version 2.1 of the standard was released in summer 2007 which promises simpler pairing procedures and updated security protocols and procedures. I haven't seen much of this in practice yet, however. Also, there have been announcements on an ultra low power implementation for very small devices such as sensors and watches by including Nokia's Wibree developments and very fast transmission rates by porting the upper layers of the Bluetooth stack over to Wi-Fi. Both announcements were also made back in the middle of 2007. Since then, no word. Anyone's got an update?
