changes to the usual DROID form factor. Think of this model as a Motorola DROID RAZR with a QWERTY keyboard which means that it should probably be thinner than its predecessor, the Motorola DROID 3. Also, it will be Motorola's first LTE enabled side slider, although we have seen the combination before for Verizon.
Since the Motorola DROID 4 is unannounced, quite obviously things like launch date and pricing is all a matter of guesswork, but there is no reason to expect anything other than a $299.99 contract price for the phone on its launch. Verizon has priced all of its dual-core, LTE enabled phones at that price while those models that top out at 3G connectivity like the Apple iPhone 4S and Motorola DROID 3 were launched at $199.99. Of course, the picture of the Motorola DROID 4 on Best Buy Mobile's Reward Zone web site could mean that the big box retailer will be gracing its RZ members will some favorable pricing on the device. And if you are not a member of the Zone, you still have plenty of time to sign up before the Motorola DROID 4 is launched.
