EA can't give an exact time frame as to when the patches will be released since that depends on MS and Sony. OMT has stated this many times. Patch 1 was submitted over three weeks ago by EA. Their hands were tied after that. Sony finally got around to reviewing it and now there is a small problem so its delayed a little longer.
Patch 2 was submitted last Friday. Its really out of EA's hands now. They estimated at least 2-3 weeks before it gets approved and released which is why they have said late August or early September. A lot depends on how many games and patches MS and Sony are reviewing right now - EA's patches just join the back of the line.
