Read the fine print: Buena Vista Home Entertainment. That means the parent company is Disney.
This promotion was created and backed by the Blu-ray Disc Association. The form you linked to in your message was the same form that would have been used by anyone purchasing an eligible Blu-ray player during the promotional period. I have a feeling that you did not provide all of the proper information. Did you cut out and provide the correct, original UPC from the box (PS3 boxes have multiple barcodes on them)? Did you provide a photocopy of the full receipt, showing the purchase price, purchase date, place of purchase, etc..?
Sadly, you have no way to find this out...or if they even received your mailing. The forms were either processed for fulfillment or destroyed. I'm guessing that your envelope was either lost or it was rejected due to incomplete information. If it was processed, you would have received your discs no later than April.
There's always hope that the package was lost in the mail and you'll be getting it eventually. But I would prepare to be disappointed.
