All signs are pointing to Apple releasing a complete refresh of their iMac product line. In the past few weeks resellers have all reported dwindling stocks. Macrumors have received a picture which looks like a piece of Apple marketing describing the iMac as having “High performance NVIDIA graphics”. Now the current high end 24-inch model does use a GeForce 8800GS but this image clearly states both screen sizes.

If they do release the aforementioned updates I expect the low end 20-inch model to use the same GeForce 9400m GPU/Chipset that the new MacBook’s use. Not only would this keeps costs down, but it is also a very capable GPU in it’s own right. Expect all other models to use the 9400m in a similar way to the new MacBook Pro, i.e along side a more powerful GPU. I also have a feeling Apple will stick a Core 2 Quad CPU in the high end 24-inch model. I might be suprised and find they’ll also use one in the high end 20-inch aswell, but I’m not so sure.
