Nvidia had plans for a chip that we keep calling ION 2, but the original version of the chip was apparently canceled back in the summer of 2009.

At the begging of the year Nvidia planned to launch a new chipset - GPU and likely brand it as ION 2. This chipset was supposed to have 40 shaders, more than two times the number or the Original ION and it was supposed to be substantially faster.

Since Nvidia came to some sort of silent ceasefire with Intel, this chip with 40 Shaders will never make it to ION 2. The product was codenamed MCP89 and it might show up on some Intel-based chipset a with high possibility of launch at Cebit next week.

The new ION for N450 and 470 chips won't be as fast and it won't be chipset to begin with. It will be a discrete chip branded as ION. Compared to the current ION will boost battery life (at least in theory) with the help of Optimus technology.
