CeBIT is coming up and with it we expect the first public displays of NVIDIA’s upcoming GeForce 9 series, but it seems GeForce 9800GX2 will only be seen behind closed doors and with an NDA signed. VR-Zone reports that NVIDIA has told its partners not to display GeForce 9800GX2 at CeBIT. At the same time, invitations have already been sent out by partners, where they’ve already promised to show GeForce 9800 cards, including 9800GX2, at CeBIT. Since the launch is slated for two days after CeBIT closes, March 11, it might be that we will have to wait until then for the first publicity stunts.
