So if you are applying precise definitions then the original spec for SD cards was for up to 2GB.
So it is unlikely, by that definition, that the RPi 3B+ - or any other system - will support a 64GB SD card, which was what you asked.
Practically, the new RPi3B+ should be able to handle any capacity of microSD card presently available. Unless you have some reason to think otherwise?
