iTunes 11 still launching this week, was delayed due to engineering issues
After its introduction during the September iPhone and iPod event, iTunes 11 was delayed from its initial October launch date to sometime in November. A more radical departure than previous updates, which included Genius Playlists and the ill-fated Ping social music network, iTunes 11 boats a new, more iOS 6 like interface, and deeper, tighter iCloud. When Apple announced the delay, they said iTunes 11 was taking longer than expected to get right. Jessica E. Lessin of The Wall Street Journal adds a little to that:
The new iTunes has been delayed a month by engineering issues that required parts to be rebuilt, according to people who have seen it.
The WSJ also believes Apple will honor their new launch window and ship iTunes 11 this week, which means tomorrow or Friday. This all comes as part of a profile of Apple senior vice president of internet services, Eddy Cue. Cue, who has traditionally had responsibility for iTunes, the iTunes Store, and the App Store, was given iCloud (then MobileMe), and more recently Maps and Siri following less than successful user experiences following their respective launches.
Services is likely the biggest challenge facing Apple in the near future, and even with Cue's reputation as "Mr. Fixit", he's got his work cut out for him.
Hopefully the extra time spent on iTunes 11 will have been well spent.
