The Motorola Droid X has been a popular phone for Verizon. It was their answer to other large-screened devices like the EVO on Sprint and the HD2 on T-Mobile. That said, the Droid X is starting to fall a bit behind in the specs department when compared to the upcoming wave of Android phones like the Droid Bionic.
It looks like a successor to the Droid X, dubbed the Droid X2, might be on its way out in time for the spring. According to HotHardware, the Droid X2, known internally as the Daytona, will have a similar form factor and design compared to the current generation device, but will add the 960×540 qHD display and the Tegra 2 platform, but sadly, no LTE.
