More than a month out from RIM’s scheduled unveiling of its BlackBerry 10 lineup on January 30, the leaks are already coming. Today, a Vietnamese website known for its Apple leaks has released a video preview of an upcoming BlackBerry 10 device codenamed “London.”

The smartphone, as shown in the video, has a rear-facing camera & flash, a microSD card slot, and a removable battery. It is also rumored to have a 4.2-inch screen, which the video appears to confirm.

The surprising thing about the video may be that the device isn’t all that remarkable. Even the BlackBerry 10 software running on it heavily resembles the Android and iOS interfaces, with a few twists. This could be worrisome for RIM fans, as not even Microsoft’s highly unique Windows Phone 8 devices have been able to capture consumers’ imaginations and make much of a dent in the iOS/Android dominated smartphone market.

Unless RIM has a surprise waiting for January, BlackBerry 10 devices could easily fall under the shadow of Apple and Samsung, as so many other manufacturers have. In fact, it might be hard for the company not to be upstaged by Samsung, who has teased a big announcement for CES earlier in January.
