Last-minute leaks of part numbers hint Apple is about to release both upgraded iMacs and Mac minis on Tuesday — along with an emphasis on larger screens for iMacs and a likely NVIDIA-based design.

French site MacBidouille on Monday detailed new model numbers that appear to confirm AppleInsider‘s discovery of six new Apple products in resellers’ pipelines.

Of these, four models ranging from MB417 through MB420 are described as new iMacs, but with a different system balance than today’s lineup: only the first model would have a 20-inch screen, while the remaining four would have 24-inch displays.

In turn, two Mac mini models, the MB463 and MB464, would represent updated low- and high-end versions of Apple’s compact desktops.

All four would be available today and ship almost immediately, according to the claim.
