Microsoft and Sony were wishing one another good luck on social media channels last week for the launch of their respective next-gen consoles – an unaccustomed outbreak of politeness. They’re also trading press releases about the popularity of Xbox One and PlayStation 4 in their early days. Microsoft said this weekend that it sold more than 1m Xbox Ones in its first 24 hours on sale late last week in 14 countries. “Xbox One is now sold out at most retailers,” said Microsoft. Sony had already announced last week that its PlayStation 4 had sold 1m units in the US alone in its first weekend on sale there, ahead of its global launch in the coming days. That’s 2m Xbox Ones and PlayStation 4’s out in the wild, then, but this is just the start of the two consoles’ battle. As we reported earlier this month, research firm IHS expects PS4 to shift 49m units over the next five years to Xbox One’s 38m (Bulletin, 13-Nov-13). We’ll be very interested to see if the new devices fuel a growth in signups to the respective Music Unlimited and Xbox Music digital music services.
