I don't know-I had 3 of these and only 1 was from the Blu-Ray-The 1st I sold the buyer responded and said it was in SD-the second buyer never responded when I asked him if he got the HDX one. So I guess you have a 50/50 chance of it being in HDX-Hope this helps (but it would have been nice it bidder #2 told me what format he got!)
