Actually, what he was clearly saying was that you don't ever see 4K resolution in theatres, because 35mm print is 4 generations from the negative and the resolution of the prints is no more than 1080p. So 1080p (in terms of resolution) is the same or better than what you see in theatres from 35mm. And I just saw the Inception too and it was projected from film and I'd say the level of detail was about as high as 720p, so I must agree with that. But it was great, film has that special, warmer feeling to it, which digital just lacks. (And the film itself was awesome too, one of the best I've seen in the last few years actually.)
