No, it's supposed to be simply "early Q3". Read the chart.

The only people saying "Q3" instead of "early Q3" are internet sites who seem to have something against the Bionic, and want to make other devices look better by trying to make the release date for Bionic ICS appear further away than it is. For some strange reason, I am inclined to believe Moto above random internet sites. I kinda figure they (Moto) may just have a little insider info *LOL*
