On twitter today Tom Warren confirmed WP8.1 for all devices but seems to imply that the Google Now rival Cortana won't be always on due to hardware limitations.

This is expected since the only phones with this technology all feature a separate chip for this purpose. The next generation of WP devices(1320, 1520) with Snapdragon 400, 600 & 800 have a DSP chip for background tasks. Pity, let's hope there's a lot more to Cortana than always on voice recognition.
