More new iPods on the way...

Apple plans to introduce more iPods before the end of the year, a company executive said on Tuesday.

Executive vice president Tim Cook didn't say whether the new iPods will come at a press event Apple has scheduled for Wednesday morning. But during a conference call with analysts, he suggested that the iPod Nano won't be the last new iPod of the year.

Cook said: "Over a year ago, we set out to create revolutionary updates to our core iPod line-up. Last quarter was the final quarter for the older products. We think we did rather well with the prior line-up and believe that we will do even better with the new lineup that we have for the holiday season, including the new iPod Nano and some very innovative new products that we have yet to introduce."

There has been considerable speculation that Apple might add video-playing abilities to its hard drive-based iPod line-up, though some have said that possibility is less likely given Apple CEO Steve Jobs' negative comments about such a device and the difficulties associated with making available the kinds of commercial video that would make such a device popular.

Although record-label executives have confirmed Apple has sought wide-ranging licences to sell music videos through iTunes, movie studios have yet to make feature films similarly available.

GartnerG2 research analyst Mike McGuire said: "If you're talking about a video iPod, what would drive the demand? Music videos? You have a whole generation of people already conditioned to getting those for free."

Apple has continued to grow its iPod sales, though the growth has slowed from the meteoric rise of several months ago. In the company's most recent quarter, which ended 24 September, Apple sold 6.45 million iPods. That's three times the number it sold a year ago but up just five per cent from the prior quarter.

One challenge for Apple is that demand for the iPod Nano strongly outstripped its ability to supply the flash memory-based music players. The company said on Tuesday that its efforts to meet demand for the Nano are being crimped by a parts shortage.

During the conference call, Cook said: "It is a component constraint. I don't want to go further with which one [it is]."

Apple said it shipped one million Nanos during the first 17 days the player was on the market but said demand was far greater and that the company does not know when it will have enough supplies to meet demand.

On the Mac side of things, Apple noted that its inventories are below its desired range. The company said it hopes to correct that but did not say whether new Mac models would be the ones used to replenish shelves.
