The Bluetooth standard receives a couple of improvements promising more useful devices-- the Bluetooth Special Interest Group (SIG) updates it to version 4.1, and Broadcom combines it with wireless charging on a single SoC.
Bluetooth 4.1 allows for devices able to "remember" lost connections for longer, with automatic reconnection as soon as devices are in range. It improves on the coexistance of Bluetooth and LTE radios on the device, and adds bulk data transfer capability.
Devices running the updated standard will also be able to run as both peripheral and hub-- the Bluetooth SIG gives the example of a smartwatch acting as a hub by gathering information from a heart rate monitor while simultaneously acting as a peripheral as it pushes notifications to a smartphone.
For the future the Bluetooth SIG plans to add IP connectivity-- allowing devices to communicate over IPv6 via Bluetooth radios to create a "fundamental wireless link" in the so-called Internet of Things.
