I'll point out that it is very clear that there will be BLE support in stock android(Samsung supports BLE via a device specific SDK) after the Google IO release of the Android. Google's Glass supports BLE based on the FCC approval documents. It appears that BLE support was prioritized after the Bluetooth stack rewrite that happened in 4.2. The Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10 all have hardware capable of BLE that should be available after the update.
