Japan's NTT DOCOMO just announced a March 31st retail offering of LG's Optimus Pad. The Honeycomb tablet listed as model L-06C is the same 8.9-inch 1280 x 768 pixel slab known as the G-Slate 'round T-Mobile subscribers. Besides its 1GHz dual-core Tegra 2 processor and internationally compatible 3G data and GPS, the Optimus Pad's most noteworthy features are the stereoscopic rear-facing video cameras capable of 1080p 3D capture which can viewed directly on the L-06C with a pair of passive glasses. Unfortunately, NTT DOCOMO is mum on pricing. Remember, although T-Mobile originally hedged with a spring launch (recently rumored for April 20th), LG told us that it'd be arriving on US soil in March. So... T-Mobile, anything you'd like to add before Thursday?
