That depends on what you mean by an 8x10? If you mean a matted 8x10 (7.5x9.5 inches) at 300dpi you need 7.5mp in a 2x3 format sensor. So, the 8mp figure is right in there, while 6mp is a bit small. My little Oly is 5mp but in a 3x4 format so it produce a 256dpi image at that size (7.5x10 actually) as does the 6mp 2x3 format sensor in the Pentax D-SLR's, but with fewer wasted pixels. If you want an 8x10 (or 8x12) 300dpi full bleed image then you need a few more pixels. However 9mp will do it with a tiny bit to spare. If you want 360dpi then you need a bigger sensor, and if you are will to settle for 240dpi a smaller one will do. So, as I said, it it depends upon your definition of a near perfect 8x10.
