They're still buying up assets.  They've claimed that there is no QE going on, but that just doesn't seem possible.  The US Govt is still running a -400Billion dollar deficit. That money has gotta be coming from the Fed.  This is straight from the US Govt financial website.     

At this point, they will probably start doing exactly what Draghi has started - buying up market indices directly.  They may not even announce it, though and just keep it under wraps.  All the rules have changed.  I really don't think they will let markets down at all.
