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

[Oyvoyvoyv]

Well, ask yourself this question.

Will people who don't own WoW buy WoW because of this expansion?

If not, there are not very many console and WoW owners, probably ala 20% of the relevant crows, so around 2M.

This means that 3% of the console owners are going to buy 1 less console game this holiday.

Hardly signifficant.
