I don't think they give feedback anymore. I would check the waitlist chat transcripts on Fuqua's website if you have not done so already. I know of several people who were taken off the waitlist in June last year and some in July, so I wouldn't lose hope. Also, I found Fuqua to really like correspondence, so if you haven't done so already - email them and tell them how pumped you are to still be considered, and that if you were admitted, there is no doubt that you would attend.
I think the largest factor affecting Duke's waitlist is going to be the waitlist of other programs such as Kellogg. Kellogg still has spots open, but are waiting until the Round 3 deposit date to see how many spots are filled by Round 3 offers. In my case, I'm in at Duke, but waitlisted at Kellogg. It would be hard for me to turn down Kellogg, which would then most likely open a spot at Duke in June. Again, the problem is uncertainty. Hang in there.
Thanks. I know that they had the chat a while back, but didn't know that the transcript is stored on the website. I have sent Fuqua a couple of updates, which include the results of my annual evaluation at work, a salary increase, new projects and my 100% commitment to matriculating if they were to take to me in. I am actually contemplating on making another visit sometime in June as well since I have been planning on hanging out with a friend near Durham around that time. Does anybody know if they are they open to WLers visiting campus?
For your sake and mine, I hope Kellogg accepts you. Then again, if I end up taking somebody else's vacated spot, I hope you choose Fuqua over Kellogg anyway.

I'm in the same position (R3 WL). Applying again for EA or R1 next year makes a lot of sense - better shot to get in and possibly with some $$, assuming you can address the weaknesses in your application. It sucks to go through the process again, but without any idea of my chances of getting admitted off the waitlist, I think it is better to assume the worst and start getting ready to reapply. WL is terrible.
Have you been admitted anywhere else? If so, what's the likelihood of you choosing to enroll this year vs. waiting to reapply later this year?
My main concern is that submitting my application in March and then sending in two updates since (one in April and another last week) would leave me with nothing else to write in the "What makes you a stronger applicant this year?" essay. Does anybody have any statistics or anecdotal information on how WLers have fared as reapplicants?
@mbahubby: I believe the R3 deposit deadline is Friday, May 20th. Therefore, there's a possibility that people will be admitted off the WL as early as Monday, May 23rd. Also, based on your profile, I think I might have met your husband when I interviewed on campus in April.
