will the new wow expansion put a dent in possible console sales?

[Ail]

BC released after the holydays, not at the same time than the mass of console titles released for holydays...

The software impact will be more than 1 title for those peoples playing both wow and console ( like I am ).
Issue is not cost but the time they will invest in wotlk instead of investing it in new games...

Right now I play wow at most 4 hours a week ( time it takes to clear Sunwell). Once wotlk is out, for a few weeks I will be playing wow 40h/week for a few weeks. Time I currently spend playing PS3 games so there will be an impact...
