I'm not there (would like to be) but am happy to provide instant commentary. You may read my predictions .
There is this year the Calvinist controversy in full bloom. Moderates predicted this a couple of decades ago while on their way out the SBC door. The 2nd VP position is perceived as a contest between the Calvinists and Traditionalists.
The most significant news is that the SBC will elect a black president tomorrow but the buzz is for the calvinist/traditionalist stuff.
