To eternity (and beyond.....)
Email message from QL HR is that they will updating those with conditional acceptances shortly (next week or so).
Based on other information in the same email it would appear that the program is still going, albeit slower, and that conditional offers (my offer is pretty much identical to yours by the sound of it) are still valid (they are still asking me for copies of documentation etc).
What they haven't done is screen any new applicants (or even give answers to some they have screened recently). This would seem to imply that those 'in the system' are still in the system but I guess they could still rescreen those on file to see who they really want.
Sorry, not a definitive answer but best I can offer,
UTR.
