Will the PS4's First/Second-Party be more influential to hardware sales than with the PS3?

[VicViper]

I don't think so, honestly.
Because the largest chunk of PS3 exclusivity came from Japan this gen. Most, if all, western games were not exclusive.

And I think Nintendo will put a tougher fight there now.

EDIT: My post is for 3rd party only. 1st party good as always.
