Nokia, Motorola to unveil new phones at the 'worst time:' a week before Apple

The events from Motorola and Nokia are being staged at the "worst time," in the eyes of analyst Brian White with Topeka Capital Markets. Joining them will be HTC, which has an event scheduled for Sept. 19, one week after Apple's event.

"Ultimately, we believe Nokia, Motorola and HTC will regret launching important new smartphones at the same time as the world's most anticipated consumer electronics launch ever, the iPhone 5," White wrote in a note to investors on Wednesday.

He expects that most of the smartphones unveiled this month by Apple's competitors will have expected features like larger screen sizes, faster chips and high-speed 4G LTE data connectivity. But without Apple's "vertically integrated digital grid," White doesn't think competing companies will have much of a chance against the new iPhone.

"Apple offers the ability for seamless connections across devices which has differentiated the company's digital grid, and this experience has improved markedly with the introduction of iCloud," he wrote.

And while competing brands like Nokia, Motorola, HTC and Research in Motion have seen their brands deteriorate, Apple's continues to strengthen. Because of that, White said he wouldn't be surprised if HTC, Nokia and RIM are no longer standalone companies in the next 18 to 24 months.

Interest in Apple's next iPhone is at a fever pitch after the company sent out invitations on Tuesday to a media event next week. The company is expected to unveil the "iPhone 5" in its keynote presentation at San Francisco's Yerba Buena Center for the Arts at 10 a.m. Pacific, 1 p.m. Eastern.
