"With the ferocious force of Verizon 4G LTE, the Droid Bionic is an all-powerful, unstoppable machine." Pretty graphic language, isn't it? That's the opening line in this leaked Best Buy Mobile promo material that we've received today, talking up a phone that had been delayed and sent back to Motorola's drawing board after its CES 2011 introduction for "enhancements" -- presumably in response to the Atrix 4G's beefier spec and feature lists. Though the ad doesn't tell us anything we didn't already know, this would be the most official confirmation yet that the leaked device going around in recent weeks is, in fact, the redesigned Droid Bionic -- a little more squared-off (and a little shinier around the edges) than the unit we'd seen in January. The "Coming Soon" note below the picture doesn't do us much good, but Android Central's latest intel has it pegged for early August; none of Verizon's current LTE handsets are dual-core, so it might just be worth the wait.
