I just asked Derek for an update and here's what he sent:
The 1.06 PC Patch (and associated DLC) is approved by MSFT and ready to go. However, in order to actually release it, we need to simultaneously release on both GFWL and Steam. And for that, we need the signed .cat and .cfg files from MSFT for the Steam version. They haven’t sent them yet; they tried last week, but there was a "mishap". We should have them any day. That’s the only thing holding up release at this point.
The 1.07 and 1.08 patch source code was just received after the holidays, and Q-LOC is currently working on integrating it. 1.08 is the 2013 rebalance patch, which hasn't made it to consoles quite yet. No ETA on these until after 1.06 is live.
