The G3 is adding a micro lens array which will allow for increased brightness and improve viewing angles. The marketing on increased brightness almost always points to peak brightness, which I suppose is good if you specifically need it for a bright room. I think it's better to view it as greater efficiency - same perceived or measured brightness at less power, which means less chance of burn-in and reduced temporary image retention. No major new features on the C3.Yes, and they have it in a 77" version this year. Early reports are good; they weren't supposed to be sold before 2/21, but there are a couple of people that managed to purchase last week and have been providing information on another forum I frequent. Curious to see how the C3/G3 will stack against it when they come out.
