Just got the call from my bike shop. My wheel is back. New 88 hub, new spokes and my original rim. When the bike shop called I asked them about their original conversation with Zipp and they told me that Zipp had said they replace the hub and spokes for free and if the rim is damaged they just charge a nominal fee for a replacement rim.
Maybe it's customer service roulette, although my rim was in very good shape (I did remove the Zipp stickers btw). While it had approximately 10K miles on it, the brake surface was not worn at all and there were no cracks. With the new hub and spokes it is like new. I would not have been happy if they tried to do the 60 switch on me.
Just got it back. Looks to me like a V9 88 in silver. New spokes, original spoke nipples.
