I think it will grow a lot slower than IPv4 because with rational planning, few organizations should need to add more 
prefixes annually, the way they had to in IPv4 due to scarcity based allocation policies.

The implication of this statement would seem to be that the reason the routing tables are growing is due primarily to 
allocations and not deaggregation (e.g., for traffic engineering).  Does anyone have any actual data to corroborate or 
refute this?
