I found this comparison fairly interesting, so I thought you guys might, too.
I took current total sales approximations for all systems from the current generation and last generation, then divided them by the number of months they've been out for (rounded to the half-month). Calculations are measured out to when their successor was released (if they are last gen), or in the case of the Dreamcast, it's rounded to when production ceased.
These are solely approximations, and I didn't waste that much time putting them together, so don't bother checking for perfection. I just thought it was interesting, though, seeing how everything compares.
DC - 0.38m
PS2 - 1.44m
GCN - 0.36m
Xbox - 0.41m
DS (both) - 1.4m
DS (lite only) - 1.7m
PSP - 0.76m
Xbox 360 - 0.51m
PS3 - 0.49m
Wii - 1.19m
Two things I found particularly interesting:
(1) Dreamcast, while it was alive, sold at a better rate than the Gamecube. Would it have possibly done BETTER than the GCN, had SEGA continued production?
(2) People claim that the Wii has a chance of passing PS2 in sales, but the current sales numbers disagree with that. Of course, sales could easily pick up (as PS2 sales followed similar trends within the first year after launch), but if trends follow current rates, Wii will likely be around 95m after a similar lifespan (giving 80 months between system launch and successor launch).
