Motorola's Droid X2, the follow-up to one of Verizon's most popular Android phones, is set to launch in stores on May 26, according to internal documents.

The Droid X2 will also be available by direct fulfillment starting May 19, Android Central and Droid-Life have reported. No word on price, but I'd be surprised if the Droid X2 cost more than $200 with a two-year contract.

The original Droid X launched in July 2010 and immediately sold out. Sales figures aren't available, but I can say anecdotally that this is one of the most common Android phones I've spotted in the wild, and Amazon listed it as a best-seller during Cyber Monday last year. The Droid X was also influential, as the second Android smartphone to use a 4.3-inch screen. (The first was HTC's EVO 4G.)

Now that ten months have passed, the Droid X2 will deliver a much-needed spec boost, with a 1 GHz Tegra 2 dual-core processor, a qHD display with 960-by-540 resolution, and HDMI mirror mode. Like the original Droid X, the new model will have 8 GB of on-board storage, but it'll also include an 8 GB microSD card preinstalled, compared to 2 GB in the old model. Strangely, the Droid X2 will still lack a front-facing camera. It'll likely run Android 2.3 Gingerbread with Motorola's Blur interface on top.

Given the lack of major changes in the Droid X2, I don't expect Verizon to make a big deal out of this phone. The carrier seems most interested in pushing smartphones that support its LTE 4G network, such as the Droid Charge and HTC Thunderbolt. When Motorola launches the 4G-enabled Droid Bionic this summer, I suspect it'll become a flagship smartphone for both Verizon and Motorola.

But if you're not interested in Verizon's 4G phones -- and the battery drain that's reportedly associated with them -- the Droid X2 might be a solid alternative.
