It will be interesting to see if Uncharted 4 can maintain the sort of success that UC3/LoU enjoyed, or whether that franchise too will see a decline. Things certainly have't been pretty for games like Gran Turismo, Halo, Tomb Raider, Little Big Planet, even Forza. Then again, unless I'm mistaken, games like Shadowfall and InFamous Second Son actually saw notable franchise growth in terms of sales.
At least hype is through the roof and we haven't seen any negative articles from press, it's all praise praise.
Uncharted 4 should be up on UC3's 700k debut imo barring a majority negative reviews.
People are frothing at the mouth for that game.
I think close to a million for April NPD is doable.
