As the clock ticks towards September 8 (the rumored release date of the Motorola DROID Bionic on Verizon) more and more sightings of the famed DROID Bionic have surfaced, with photos getting clearer each day.

Just a few hours ago, we covered the story about a really cool photo showing the Motorola DROID Bionic flaunting its ridiculous 4G LTE speeds.

More clear images have arrived today, courtesy of an unnamed source who sent Engadget photos not just of the DROID Bionic, but of its other rumored sibling, the Motorola DROID HD.

The new photos say nothing new about the DROID Bionic, but they do reveal a few exciting features of the Motorola DROID HD.

The photos suggest Android 2.3 Gingerbread to be onboard. Slots for SIM and microSD cards are on the DROID HD’s left side, while the volume rocker and power button are on the right side.

A slight horizontal bump on the back of the handset houses the camera array. The Motorola DROID HD is carrying an 8-megapixel primary camera with 1080p HD video capture capability–just like the Motorola DROID Bionic does. The LED flash and the speaker also sit on the back hump.

Underneath the backplate is a large but thin battery that is possibly removable.

Click on each photo to see a larger size:

Engadget notes that the Motorola DROID HD is of almost the same thinness as the Samsung Galaxy S II and that the screen size is 4.5 inches (presumably of qHD resolution, or even 1280×720). Both the Samsung Galaxy S II and the Motorola DROID Bionic have 4.3-inch touchscreens.

Could this device be the Motorola Dinara (the rumored DROID Bionic successor purportedly carrying an HD screen bigger than the Bionic’s)? Or probably a toned-down version of the Dinara?
