As the OP said, it's probably not because they didn't have time to show it at E3. My guess is that they didnt want any bias going into E3. They may have been worried that people would have a certain stigma towards X1 and the games they showed if there was already a preconception that the system was overpriced. But now that no one can really argue about the price anymore, people may be more receptive to what they show at E3.
