i don't think any hardcore game will decrease wii sales.
simply demography doesn't even get close.
nintendo core doesn't like shooters unless its golden eye (that its rumored to go XBLA).
soccer mom/parents/gramps won't buy gore M+ AAA title not matter the reviews for them or especially their kids that are the one that buy games reason why gta4 mgs4 didn't do much for 360/ps3 but did increase both consoles sell together over 600k for the week.
but LBP got a HUGE APPEAL.
from core hardcore, parents.
the only thing stopping this game to be a major success its the ps3 price but i think this game will have AWESOME LEGs and continue selling a long after release.
