Totally possible if the "2 weeks" at Costco is true.But this news does not mean that it will affect the Verizon Release.. Although I do not think it will be the 4th. I still think that it will be released in Mid to late August!!!
Costco is getting the Droid 3 this coming Thursday. My brother is waiting very impatiently. That's 2 weeks after the official in-store VZW release. Just saying.
