Remove low ISO film, install high ISO film, shoot.
With a DSLR, ISO range, DR and noise are fixed at the time of purchase. It's tough to say, "I will never need to shoot at ISO 6400 for the life of this camera." It's a marriage, not a date.
When I got my K-7, the K-x was the only available choice for high-ISO, so I did make that assumption. I got a lot of extra features vs. the K-x, and I like that. With a K-5 among the choices, I don't know; I might have just come up with more money. I have lenses that make up for the ISO, though.
