Right now, there is a hard-coded limit of 1 megabyte per block. @p{par}

If we assume that limit never changes, that gives: @p{brk}
 1MB per block * 6 blocks per hour * 24*365.25*200 = 10,519,200 MB @p{par}

... or 10.5 terabytes for the maximum size of the entire blockchain over the next 200 years (somebody check my math, I'm really good at dropping zeroes). @p{par}

I expect that in 200 years 10 terabytes of storage will cost a few pennies. @p{par}


@p{hrule}
Now whether or not that 1 megabyte per block limit should go away is hotly debated, and will be debated more and more as transaction volume increases.
