More interesting of course is contemplating what President Bush's renewed funding of nuclear spaceflight is like to bring us in the near future. Imagine a spacecraft taking off with virtually no weight limitations, and a much, much cheaper cost per ton of cargo than is currently attainable with chemical boosters.
Personally my bet is that the next big 'dot-com' ('dot-bomb'?) investment phase will be biotech, and the one after that will be space exploitation.
