Ambiguous comments by Elop during his keynote at the New York announcement suggested that Nokia may miss the holiday season in a lot of markets. Elop said the new Lumias would be sold in some select markets, but didn't get more specific about availability, pricing, or carriers. AT&T and T-Mobile sold the earlier Nokia models.The Lumia 920 will run Windows Phone 8, the next version of Windows. Nokia also introduced a less-expensive Lumia, the 820. With Apple expected to unveil the iPhone 5 next week, it's even more important for Nokia to get this next generation of the Lumia line right, given the struggles it's faced trying to remain relevant in the smartphone game. The big question now is whether it can ship enough of the new smartphones to meet holiday demand.
