Sony only bought the camera business of Minolta to get hold of their technology, patents and experience/brain power. none of the camera lines survived. The more profitable reprographics business still carries on asKonica Minolta. Some parts like binoculars and film scanners were left to die.
I find it hard to think what Fugi would want to keep out of the camera side of the purchase of Nikon. If they had wanted to compete in the Full frame market they would have already done so, the high end medium format sector has always been more their area of interest. The full frame market is only going to become more and more competitive as it shrinks to its basic core.
