I don't know if this is the right place to post this, but I found a cancelled set using the inventory comparison tool before they took it down. I typed in every set # in the 47XX range, looking for any cancelled Harry Potter sets. The only one I found was 4724. Judging by the set number and the parts, it would have been one of those $10 sets with two 8 x 8 plates and the cardboard backdrop. See: 4721, 4722, 4723. I haven't seen anyone else on the internet mention it, so I might be the only person who knows about it. I've never posted anything to this site before, but I saw the VezonWireless video, so I thought I'd post my findings in this thread.
