It is rumored that NVIDIA's GeForce GT 300 new flagship graphics card won't arrive until October this year, a source leak with one of NVIDIA's partners may have hinted to this . They tell the Inquirer that the first actual production models will be ready October 15th following a tape out, or a first submission for manufacturing, in June.

Whether or not NVIDIA will make its target is nonetheless called into question. The company is likely to have the first revision of fully testable silicon on August 1st but may take as much as 3 months after testing to manufacture enough for the first batch, putting an actual release in mid-November at the soonest. Any need to significantly revise the card would likely push the actual release further.

GT 300's feature set hasn't been leaked, though it makes sense to bring support for DirectX 11, OpenCL and newer OpenGL and will likely use NVIDIA's version of 40 nanometer manufacturing to improve performance and reduce heat versus today's 55nm parts.
