Motorola CEO Sanjay Jha confirmed on the cell phone maker’s fourth-quarter earnings call that two of Motorola’s highly anticipated upcoming devices will launch next month. AT&T’s upcoming convertible superphone, the Motorola ATRIX 4G, and Verizon Wireless’ monster tablet, the Motorola XOOM, both look set for a launch at the end of February. The ATRIX 4G features a dual-core Tegra 2 processor, a 4.3-inch 540 x 960-pixel display and an option laptop dock that converts the device into a full-size smartbook. The XOOM is a Honeycomb tablet that sports a 10-1 inch display, full HD support and the same dual-core Tegra 2 processor as the ATRIX. Jha seemed more secure in the ATRIX 4G’s launch timeframe during the question and answer session at the end of the call, saying that the XOOM might be pushed back slightly to March. But Jha also reaffirmed that the 4G LTE-enabled Motorola DROID BIONIC and the LTE hardware upgrade for the Motorola XOOM are both on track to launch at the end of the second quarter.
