I doubt nVidia is holding back development....and i have a hutch that the 9800gx2 is not going to be there top offering......look at the realease schedule of the 8800gtx and the 8800 ultra....which was about 6-8 months....so nVidia might be spending their rescources on the new product. the 9800gx2 is probably just a temporary stopgap to take the fps crown back from Ati
