3.0 is a good update, most of the benefits is on reducing errors and increasing overhead efficiency.
but for 4.0 theres not much on the table as of now.

they could improve latency while improving bandwidth, as i've mentioned increasing the base-clock to 200Mhz would double the bandwidth while halving latency.
the only down-side to this is the data path would be shorter, meaning you can't use a very long ribbon cable anymore.

if they truly want PCIe to become much better, specially for SSDs, they have to reduce latency.
similar to a 144Hz monitor with horrible input latency, having high bandwidth would worth less if the device can't respond fast enough.
