Remember how Lew Wolff in the beginning of the season that he expects to make an announcement about the A's future home by the end of the season? Well, it appears that he now expects to push that date out until perhaps the end of the year. He admitted as much during Robert Buan's interview with him after today's comeback victory. Wolff said that things are progressing on the ballpark front, but didn't get into any specifics. He also mentioned that he's part of baseball's Enterprise committee (which covers branding among many business-related aspects), and that he wants to be part of the Advanced Media committee (internet).
Honestly, this shouldn't shock anyone. These deals can take a long time to gestate even if on the surface they appear simple. The possible delay may be interpreted any number of ways. I'll stay away from that kind of speculation for now.
