Now see I agree with you that they seem weirdly adamant that the PS4 needs first party stuff when it is the most popular platform for the third party stuff. But you gotta understand that from their perspective, with access to all the consoles, they want something to stand out, and there's not much standing out this year for the PS4 that you can't get anywhere else.
For people who aren't in that situation though, it's a very weird complaint.
But when they talk about it they make it sound like its a problem for the market as a whole, and the fact is that's it's not. It's just a problem for people like them who own every system.
And if No Man's Sky makes 2015 it won't even be a problem for them. Also Persona 5.
