I'm sorry, but I wasn't talking resolution charts. I was talking about resolution at the sensor. It would take a full frame lense capable of generating a properly resolved image for a 80mp sensor to be able to be used on a 20mp 4/3rds camera for proper resolution at the sensor of the camera. And Olympus and Panasonic did not put out a statement indicating that certain lenses would not have enough resolution to be used on the new 20mp sensors. They planned for the future. I suspect that the upper end lenses are all capable of resolving an image for a sensor of 25mp or maybe even a little more. If it is capable of resolving for a 25mp sensor, it would require a full frame lense capable of resolving images for a 100mp full frame sensor. I do not believe that such a full frame lense exists. And if the 4/3rds lenses are capable of resolving better than 25mp for 4/3rds sensor, that would require a full frame lense capable of resolving beyond a 100mp sensor resolution to be able to be used for the 4/3rds sensor.
So the correct answer for the OP is to buy the sharpest lense for his format that will out shoot his sensor. Then as he replaces his camera bodies in the future with higher megapixel sensors, he will not be obsoleting his lenses. Also, using a larger format lense on a smaller format system can be done but is not advisable and could end up being very counter productive.

Most sharp lenses remain sharp. Most threads, though, get dull very quickly.
