Has Flash PCIe market reached the peak?

Whenever there is a new idea, a new movement, a new music style, any new thing in any aspect of life, we can observe more or less the same timelines during its lifecylce. These days, I’m starting to see the same traits in the Flash PCIe market.
At the beginning there is the explosion of a new market. Someone launches a new technology (or it can be a new music genre, this example works in different areas), and suddenly a completely new market has born. They had an idea, they identified a new need from customers, or the same need that could have been solved in a different and better way. In this case, the bottleneck created by old bus connectors like SATA and SAS were preventing the complete use of insanely fast Flash memories. By connecting the same memories directly into the PCIe bus, that bottleneck was removed and customer could experience better performances.
