Accurate only for that moment.  Once 10.5 million bitcoins have been issued, the block reward cuts in half.  This happens roughly every 4 years, and continues to cut in half every additional four years until the block reward drops below a single bit on the 64 bit integer that holds bitcoin values; after which point no more bitcoins will ever be issued.  This algo results in a total monetary base for bitcoins that is highly predictable and trends towards a (calculas) limit of 21 million bitcoins, but in practice will cease somewhat before hitting that limit.
