Thanks for the replies all. The reason I asked is because I entered at West Kowloon Station, and all of the forms intentionally had the departure card section removed. I reentered to HK via Futian Checkpoint, and I didn't see any extra forms at the counters like I had in the past. Combined with the report from klashn this morning of PVG also having the departure cards removed from the arrival cards I was wondering if something had changed.
