I interpreted his remarks about when the OTA was to come to mean that we'd likely hear about some uses getting it well before the end of this month (I've given up on date predictions

).
I have no idea when it will come, beyond that. I liked his, "in a matter of days, not weeks," but that was not all that influenced my interpretation of a likely time frame. We talked about it for quite a while, and I posted four significant highlights of the conversation.
Other things causing me to think of it as this month were the many references to "finishing up the Droid update, which is a moving target as we sell the non-upgraded Droids in the stores which will need to receive it," and "deployment of new servers for the Eris OTA, which will probably overlap the Droid OTA," as well as the longer portion of the conversation having to do with the size of the Eris update and just what is in it.
