We are sailing in the same boat. Hope to see some movement soon.Every week the status bar reduces by 1 week saying lesser days remaining to complete the PR process.. But no change in the steps... Background check still in IP1 since October...
BTW, this morning I saw a change in my profile - The application status changed from "You may not hear from us for a little while, this is normal. Most progress happens closer to your estimation completion date" to "Make sure you read your messages and take action when we ask you to. This will help move the application process along."
There was no ghost update and no change in any other statuses either. Still in IP1. Don't know if this change signifies anything, but its better than no change at all..
