My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

For the past year, 5G cell technology has generated a lot of excitement–and a lot of hype. If carriers won’t build cell towers for current technology, they aren’t likely to build even more towers for 5G. There are impressive estimates for latency for 5G, but reality has a tendency to be harsh on such predictions.
