Nvidia Ion 2 chipset coming out late this year?

A wild rumor about an upcoming release of an Nvidia Ion 2 chipset has surfaced on the web. Q4 2009 seems like a weird date to launch a product, but February is typically a “refresh” time for the PC industry, so samples must be out there already if that was true. In any case, the rumored performance would be 2X the graphics speed of the current Ion chipset. Ion is also known as the GeForce 9400M and is found in a number of laptops (like the Macbook Pro) or netbooks. It works with Core 2 or Atom Intel processors. For now, I’ll assume that the thermal envelope and power requirements are similar to the first ION chip. Of course, that’s just a rumor.
