You're waaaay underestimating the projected spread of Vista. Most new computers sold are on Vista, and most new high end cards support DX10. At the rate technology is progressing, all cards will soon (2-3 years, if that) be DX10 capable, and in a few years Vista will become ubiquitous. You will see most users taking advantage of DX10 way sooner than you think.
