PS4 has been down YoY and from the NPD tracking thread thus far, it's very clear Pokemon, anticipation for smash and actual bf deals are going to be a big factor this year for the Switch. I fully expect ps4 to beat the Switch on the day though. I just don't expect growth.
Now we are talking about two different things.
One is competition. And I am saying that the same competition you speak of has been there all year round and it has not stopped the PS4 from winning nearly every single week thus far. So I don't see how it suddenly is going to be a je,factor now. You also cite some games and deals for the Switch.... the PS4 has its own games and deals too.
Two is growth and you talk about the PS4 being down this year. Well thats to be expected as its already sold over 80M consoles, is over 5 years old and still had an MSRP of $299. But now we are talking about it being cheaper than its ever been especially since its coming with a free game. I am not expecting it to suddenly sell better than last year overall but i at least expect it to have a better november this year than last year...... barring any stock issues that is.
