Especially if you stop allocating TCAM memory for the much larger v6 addresses. I hate to think how much memory is sitting out there in routers, configured for 128 bit v6 addresses and never used...

You only need 64 bits for routing v6, and since the address space isn't fragmented the routing table ends up at a similar efficiency level to the v4 one - probably better once you take into account not needing CIDR.
