The idea that you "won't have grain" is somewhat misleading.  When you
upsize to 11x17, you will have the equiv of grain in the form of digital
artifacts.  At even 8x10, I can tell the difference between a 35mm film
image and a 6mpixel Camera, and it is even more obvious at 11x17.
Realistically, a 6mPixel camera is equiv to 4000dpi scan of 35mm film.
Which generates some amazing images, but still doesn't quite match film when
you enlarge it.

Sure Genuine Fractals soften out the artifacting you get from the lack of
DPI, but they can't make up for lack of tonal content etc.

Save your pennies for when D1s technology makes it down to $2500, or get the
10D as a camera to use when you don't really intend to go much bigger than
8x10

You're right that you won't get _super_ sharp images from a 6Mp camera at
11x17, but they'll still be quite sharp at 180ppi. I like the results I get
with a Canon 10D and an Epson 2200. For some subjects with a lot of sharp
lines, you can use tools like the Geniune Fractals plugin to upsize, because
it does a good job of artificially preserving edge sharpness. Another
alternative in some situations, is to shoot multiple shots and stitch them
together.
