Sprint Premier Customers can get the 3D now
....and Sprint will waive the upgrade fee.
According to the email, it appears to be available through their website only. HOWEVER, I'm sure it can be haggled in their stores on the 24th.
If Best Buy agrees to honor their promo, I'm sold. The Buyback Program basically gives away the 3D for free (or @ a great discount if you didn't sign up for it @ the time and just trade in your phone w/ them for an $80 in-store credit).
Either way, this sounds promising...
