The current Z6II sensor has a pathetically slow scan speed, so it doesn't matter how fast the EXPEED or however many they have you can get the data off the sensor fast enough and the rolling shutter will still be vile and the electronic shutter will be useless for fast action photography. For comparison, the Canon R6 II sensor is > 4x faster in scan speed. If Nikon continues to use Sony's ancient slow sensor tech while not insisting on faster scan speeds they are frankly a joke. Also, the price would only be $1K less than the awesome Z8, which has 46MP, stacked sensor, 8K, bigger buffer.
