I was having a twitter discussion earlier today as to whether 2G/3G should be switched off to make room for the more efficient 4G/4G+. While I agree with regards to the efficiency of 4G/4G+, there is still plenty of room for existing technologies, including 2G for a long time.
While 5G is great and as can be seen in the picture above, a very optimistic picture has been painted with regards to LTE/5G.
Small cell forum recently held a workshop on 5G in Rome. Though it doesn't say explicitly, I am assuming the focus was Small Cells and 5G. It wouldn't be surprising as most of mmWave deployments would be comparatively small as compared to macrocells today.

I like this picture below as it shows that there are practical problems to solve today then worry about the 5G deployments of 2020. Having said that, the mobile community has to start preparing for it now to be ready by early 2020's
Huawei had another interesting concept of how 5G HetNets will look
Nokia suggested that the lessons learned from Small Cells will help vendors with 5G deployments.
