Why isn’t the Samsung Galaxy S II coming to Verizon Wireless? Three words can answer that question: Motorola DROID Bionic, which looks like it’s going to have all the limelight all for itself when it launches this September 8 without any other powerful superphone such as the Samsung Galaxy S II to steal its thunder.

With the days fast flying by and September 8 fast approaching, we’re getting more than just our buffet of leaked images of the Motorola DROID Bionic. We’re getting video previews, too.

The latest one is the most extensive hands-on preview that we’ve come across so far for the DROID Bionic. It not only shows the various screens and widgets but also demonstrates the snappiness and performance speed that make a lot of people think it’s worth waiting for after about 8 months and make those patient folks feel assured that it’s okay for Verizon not to release its own Samsung Galaxy S II variant.

The video preview also shows a speed test, which demonstrates the DROID Bionic’s blazing-fast 4G LTE capabilities on Verizon. The video itself proves the almost-buttery smooth response of the DROID Bionic to every tap, drag, swipe, or flick. A bug in the interface is also demo’d, although it will most likely be squashed before launch day.

If you’re still sitting on the fence about the Motorola DROID Bionic, does this video change your mind? Going Bionic? Or moving on?
