While I believe other devices will obviously eventually get basic L3 hardware offload (which is not all that interesting and unique since there's plenty of L3 switches out there) - most of them feature super weak sauce MIPS CPUs. However few switches (in particular CRS317 and CRS309 with dual core ARMs and few others with single core ones) feature beefier CPUs which I believe will perform quite well with L3 offload in FW mode and fasttrack enabled. Making them wire-speed stateful firewalls. Which is kinda insane if you think about it.
I mean I don't think I've ever seen such thing in the wild. Performance of this monstrosity is yet to be benchmarked but I believe it really does have potential to become something like 160 gbps stateful L4 firewall. Which is incredibly impressive like holy crap...
