If You Want one Lemme Know :P
The NVIDIA GeForce GTX 690 GPU will be available in limited quantities starting May 3, 2012, with wider availability by May 7, 2012 from NVIDIA's add-in card partners, including ASUS, EVGA, Gainward, Galaxy, Gigabyte, Inno3D, MSI, Palit and Zotac. Expected pricing is $999.
Note, All 28nm Based Gpu's are Produced in Limited Numbers due to 28nm Production Cost Problems thus, TSMC ringed the alarm of both companies concerning the the Huge Demand / Limited Production Numbers and sadly both are looking for New Foundries.
Edit: "Huge Demands" The number of 28nm customers are more than double when compared to their 40nm counterparts.
Hopefully 28nm won't be killed before it's even launched we still have Nvidia 78XX Series A.K.A "GK110 / 112".
