SAS has mostly stopped growing not because of form factor changes but because Broadcom are assholes.
They basically have a monopoly on SAS interfaces having eaten up LSI.

The industry wants to ween themselves off Broadcom, going so far as eliminating SATA and moving everything including HDDs to PCIe. This is still playing into Broadcom's hands because they also own PLX as PCIe switches are going to be necessary in the future but figuring out PCIe switches is going to be easier for other firms to figure out and probably less of a patent and implementation minefield.
