Motorola Droid Bionic was announced during the CES and has been delayed for a long time. It was actually slated for a release in the second quarter, but the lack of leaks suggest Verizon hasn’t gotten the device into the hands of testers for the final push. The smartphone may not be available for purchase until the third quarter as Motorola said it pushed back the timing of the launch to incorporate new features into the phone.

A Motorola spokeswoman said, “Based on compelling feedback since [Consumer Electronics Show in January], we are incorporating several enhancements to make this an even better consumer experience.” But other reports show that Droid Bionic will be available in Costco on May 12. The most important factor that may put the smartphone in the limelight is its LTE technology. Motorola Droid Bionic is priced at $149.99 with a new two-year Verizon contract.

The HTC Sensation's price is yet to be announced but the smartphone has video-on-demand service and the HTC Watch app along with the Video Trimmer tool.
