Wait and see “how it will affect sales”?
Does this mean they actually think that a profitably large number of people buy a song, want it on another device too, and then pay for it AGAIN there, rather than face the hassle of synching it over? Thus, super-easy synching would be bad for sales? And making music simpler would not be good for sales?
Or is it really just the iTunes Match part that worries them? Do they think CD-rippers and music pirates are tech-savvy enough to get a song onto their computer, but not enough to manage the automatic transfer of that music to their other devices? And will therefore pay for the song on each device as a last resort? Thus, again, super-easy synching would be bad for sales? And getting $25/year from that strange pirate is worse than getting $0?
