New body style?

I plan on buying a Denali XL this week, but I am having trouble finding out when the body style is due to change. I have heard they will at some point look like the Silverado's, but I can not seem to find out any info.

Generally car manufacturers change body styles every 5 years. The Denali was redesigned in '01, so maybe a new one will be out in '06... Don't know for sure, thats my guess though. On another note, I just bought an '03 Denali and I love it! If you havn't driven one yet, go test drive one (I think GM currently has a 24 hour test drive) and i'm sure you'll like it.
