TOS will have more sales in Japan than Tales of Vespera will have WW.
I think TOS:DoTNW (if it is good) will be absolutly huge. It is being pushed by Nintendo and looks like it will be marketed very well. Add that to the fact TOS already has a huge cult following I think it has a shot at 500k in Japan, and 1.5 million WW.
That would certainly help to start bring the Jrpgs to the Wii.

360- 37 million Should trend down slightly after 3rd year peak
