I find it interesting that Sony has not ruled out first party updates aside from GoW & HFW, as well as not ruling out business or service updates, as they have done in past blog posts.
Yeah, I mean... I dunno. On one hand you're right, but on the other I wouldn't get my hopes up that we will get anything besides indies and 3rd parties.
But whether a secret announcement is coming or not, I'm interested to see more on certain games anyways. I'm good either way
