I was a little disappointed after looking at the NR spec, it looks like 5G is mostly a sample rate multiplier on the 30.72MHz clock. It's still OFDM 8x8 MIMO. I'm sure there is some other additions that take advantage/optimize that additional bandwidth, but it doesn't have the same excitement as going from CDMA to OFDM did.
