The forwarding hardware is generally going to be the limit, and that's going to be painful enough as we approach a half million prefixes.
I would expect that we might finally see some pushback against networks that announce lots of disaggregated prefixes. The current CIDR report notes that the 400K prefixes could be 260K if aggregated. I realize it's not quite that simple due to issues of longer prefixes taking precedence over shorter ones, but it is my impression that there's a lot of sloppiness.
