Yep, I think you're right. The new Android 4.3 ( Jelly bean ) OS is there and ready to go but not sure what ( current ) phones are compatible with the new BT SMART READY system. Once all the bugs are worked out we should start to see more Androids running the new BT.

The real question for me will be, "Will I need a new phone"? Mine can run BT but not sure yet if it will be upgradeable to the new BT SMART READY ( Low-energy ). If not than it won't matter because I'll need a new phone unless there is a dongle...what ever. Not really a big issue for me. I can wait till all the bugs are sorted out and more options are available.
