BlackBerry (BBRY) fans in the United States haven’t even been able to purchase the company’s newest flagship phone for 24 hours and BlackBerry CEO Thorsten Heins is already teasing a new BlackBerry 10 smartphone. During an interview with CNET, Heins confirmed that his company has plans to launch an “exciting” new flagship smartphone ahead of the holidays this year, though launch timing isn’t yet set in stone. “There’s one new product I’m really excited about, but I can’t really share it,” the BlackBerry boss said. He wouldn’t confirm any details about the unannounced device, though he did say that the upcoming phone “takes BlackBerry 10 to another level in terms of the user experience” — which could be somewhat aggravating news to all the diehard fans and other users about to enter into a two-year agreement when they purchase the BlackBerry Z10.
