It should come as no surprise that the next Motorola Droid is already in the works. While the company hasn't announced anything official, rumors indicate that the company has codenamed the device "Maserati" which is supposedly derived from the name of the famous Italian sports car brand Maserati GranTurismo. That said, the Droid 4 sounds extremely "fast."
So what are the specs? Again, there's nothing official, but rumors point to the typical DROID slide-out QWERTY keyboard (but sans the D-pad again), a screen somewhere around 4 to 4.3-inches, a removable battery and possible 4G LTE support. And as with the previous three DROID models, this fourth-generation installment will reside on Verizon Wireless.
Unfortunately, that's it in regards to new information. The current Droid 3 smartphone sports a dual-core SoC clocked at 1 GHz, a 4-inch qHD (540 x 960) TFT display, 512 MB of internal memory, 16 GB of on-board storage, a microSD card providing 32 GB of even more storage, an 8MP camera, Android 2.3 "Gingerbread" and more. That said, consumers will see superior specs in the Droid 4, possibly even Nvidia's Tegra 3 "Kal-El" SoC (that's just a guess) and Google's Android "Ice Cream Sandwich" OS.
With the holiday season just around the corner, it wouldn't be surprising to see this phone rear its head before the end of the year. If not then, perhaps during the Mobile World Congress 2012 event in February.
