I feel like the real improvement in aptx is not the audio quality, but the latency for keeping audio and video in sync when watching tv (or computers for that matter). I used to work in the bluetooth chip industry and there really were very few players who were competitive in the audio headset business. I don't have any real insight into the players these days, but I would be very surprised if there were more than 4 chip makers who were competitive in that space. CSR was the dominant player for audio, so it's not surprising that Qualcomm who bought CSR offers this proprietary solution. So I think it's going to be really hard for someone to make an open codec solution that competes in terms of size, battery life, cost with an IC that's targeted to the market.
