22,000,000 at the least.(DS)
The release of the Wii NSMB Wii should spur sales back up to 60,000-80,000 a week WW for NSMB DS, and it could, in a best-case scenario, take more than a year for sales to float back down to the respectable 47,000ish a week WW.(oops, didnt see Wii in the title)
I'll predict 10,000,000 LT at the moment. NSMB DS was released a year into the DS's life cycle, and became a staple for people who buy it. However, i think it's a bit late for NSMB Wii to reach "staple" status.
