There are techniques to fix that. For example, Simple Virtual Aggregation http://tools.ietf.org/html/rfc6769
I'm not sure, if hardware vendors will implement something like this. I expect they'll sell you router with larger hardware FIB instead.
As the RFC says: Some routers in an Autonomous System (AS) announce an aggregate (the VA prefix) in addition to the routes they already announce. it assumes some routers in the AS have unaggregated routing table entries. Thus, even within the AS, the RFC is not very effective. The RFC, either, does not help to reduce the number of routing table entries exchanged between adjacent ASes. Masataka Ohta
