"This gives more time before a reverse split authorization ballot needs to be sent to everyone..."
I agree with Dew that this is most probably the reason. However, I think there is a silver lining in this delay. If Cox and company had no hope of shoring up the pps past $1 in order to avoid the delisting without a reverse split, then they would have bit the bullet and made the announcemnet asking for the authorization without delay. The fact that they delayed means that they have hope to sign a meaningful partnership sometime soon that may help the pps recover...
We shall see but I consider it a good sign, especially when you couple that to Cox recently buying 100,400 shares in the open market...
