I think'll hit over 350k for two weeks. That's about 100-130k boosted and I think it'll have an impact that we don't notice in the weeks after. With so many games coming, I don't think the ps4 is going to be getting in anyway slow, even in going into it's fifth year.
Sounds about right to me, a small modest boost of ~150k (week1) ish boost, followed by a smaller boost week2.
Thats what Im expecting too.
If it does over 400k the week of release consider me surprised.
