Is 25Gbps the new 10Gbps in the last mile?

For enterprises connectivity in the last mile over the next 3-5 years do you think we’ll see the emergence of 25Gbps (SFP28), 50Gbps (SFP56), and 100Gbps (QSFP28) services? What’s in the pipeline for enterprise firewalls in gateways? Fortinet seems to be the only vendor with a handful of 25Gbps appliances with SFP28. Do you think others will release 25Gbps capable firewalls or will vendors skip right to 50Gbps or 100Gbps? I’m asking this question with complete ignorance to the costs of the associated ports and the ASICS that are capable of supporting these traffic flows. Thanks in advance!
