There's no reason to expect that every block, especially in the near term, will approach that 8MB limit. It will scale with actual transaction volume instead, as Bitcoin did before the 1MB limit became a problem -- 1MB blocks were exceedingly rare; the block growth was fairly steady until it hit the upper bound. [1] It's reasonable to expect that the block size curve will continue to rise with transaction volume, but capping out the full 8MB is unlikely for some time.
