Panasonic is rumored to be launching the Lumix DMC-G3 tomorrow, the update to its Micro Four Thirds G2. According to 43 Rumors, the new cam will be 25 percent smaller than its predecessor, and will include a 15.8 megapixel sensor and a 3-inch articulating LCD. Overall, the camera appears to have a very similar form factor to the G2, but scraps the left dial, presumably shifting those controls to the touch-enabled display. The site lists the launch rumor at its highest accuracy level (think DHS threat levels, but for camera rumors), so they're pretty sure we'll have all the details come tomorrow morning.
