I expect some form of compression will be added at some point in the future.Or they may come out with a thin client that views the block chain from multiple locations. Thant way you don't have to download the entire chain. There was also talk of creating another genesis block that hold all of the previous transactions and start over with the bock chain. But who knows we may one day have a 50 gig block chain to download.???There's also talk of working on the protocol to get the individual block size down from the current size. If a block could be reduced to 1Kb the entire current blockchain would be under 200Mb. Currently the average block size is around 10Kb, although the actual size varies according to the number of transactions.Apparently there is already the facility to support deletion of unused portions of the local database, but no client yet supports it:https://en.wikipedia.org/wiki/Bitcoin#Block_chain
