Any plans so two ethernet ports be aggregated or for SFP+ module support?

You can have multiple 1 Gbps WAN connections with the USG Flex 500.  The USG Flex 200 lists 1.8~ Gbps throughput while the the USG Flex 500 lists 2.3~ Gbps throughput for their firewalls.  Any way to get that speed to fast PCs, servers, and switches other than multiple IP addresses and ports?  There are also retail cable modems that support aggregation and 2.5Gbps ports.  Thanks
