JEDE3 -
Why not compare some of the bigger debut IPs that Nintendo had, rather than the smaller ones? After all, it's not like Sucker Punch is a random 3rd party...Their last non-PS game was over a decade ago, which puts them firmly in the realm of most other N-published titles (Sony published inFamous, too, BTW). Wii Sports would come to mind as a new IP...It sold similarly to inFamous' first week (Japan numbers for WS, BTW). Of course, we all know how this will end up when you try to compare WS Japan to inFamous WW, right?
Also, I was trying to take it in the context of LTD sales. inFamous will most likely hit ~1m sales...Which is similar to Boom Blox on the Wii, and will most likely end up south of the 360's similar game Crackdown (which debuted to 320,000 units sold in North America alone - a figure higher than NA and PAL combined on a system with far less sales).
