NVIDIA GT200: a big breakthrough expected in July?

At least according to Expreview.

The image around the mysterious GT200 seems to be clear. According to Expreview, the major breakthrough (?) Graphics core is sure to be deployed on two high-end cards as well. The 9900 GTX will logically be the successor to the 9800 GTX unveiled tomorrow, while the 9900 GX2 will replace the GeForce 18 GX9800 unveiled on March 2th. Unfortunately, we still can't provide technical details, but as soon as we get more information about the GT200, we'll get back to it right away.
