I could not find any pricing info either.
Spotify, at $9.99 a month is not that much cheaper that them of the higher res alternatives in the market right now, so the can't jack the price too much higher. But in this world inertia is a powerful thing. I am sure that there are a lot of folks out there that do not want to leave Spotify because they have it set up the way they like it, are comfortable with the interfaces and have favorites and playlists built that wouldn't transfer to another service. While we as audiophile seek out change as part of our nervosa, for most people "if it ain't broke , don't fix it" is more the way they roll. So it will be interesting to see if having the ability to move up without changing anything else is enough of an incentive for average consumers to consider better sound.
