|In case NVIDIA and its add-in-board partners only showcase the NV36 and NV38 products in late September behind closed doors, we will only see the actual products powered by these graphics processors in October or later. This leads us to conclude that there will be no next-generation NV40 products this calendar year since no NVIDIA’s AIB partners want to release two high-end products in one quarter due to very obvious business reasons. Additionally, we should also remember about 6-month product cycle followed by both leading graphics companies.||
So renewments of NVIDIA his products lineup will be in October or November. On the other side from ATI we can expect the R360 and RV360 in September. It would be highly unlikely if we would still see the highly anticipated R420 chipset this year, because it would not make sense to release it 2 months later than the R360.
