I will also keep looking as some PMR's now come with Bluetooth as well so negating the need for the SR10.
There are indeed some radios supposedly with Bluetooth capability, such as the
Yaesu FTM-10R/E for amateur radio 2m/70cm operation. That unit's Bluetooth accessory is still listed as "available soon." Depending on the frequencies and regulations, you may not be legally allowed to used that radio unless you're a licensed amateur radio operator in your country.
If possible, I would certainly recommend that you test the radio's Bluetooth for compatibility with the Sena SMH10 or the new Sena unit coming out soon, the 20S, before buying. If you do find something, please post the information to this thread.
