Announcing sales figures can be a form of hype, sure, but I can't recall a platform holder ever announcing the sales of a third party game. Not to say that it's never happened, but it sure doesn't happen often. The closest thing that comes to mind is bragging about COD on 360 outselling the PS3 version 2:1 in response to NPD or something like that.

Yes because it isn't like EA has earning reports or anything. Microsoft has no ties to the game other than money paid to EA for exlcusive rights. Other than that Respawn made it and EA published it.

TitanFall will most likely reach 6 or 7 million sales this year, or even higher, and thats when EA should announce the numbers. when TF reaches "Mega" sales, so people can compare it to the "Mega" franchises. This is why i dont see EA's lack of TF announcments as a sign of TF under performing. Fact of the matter is TitanFall competes with CoD, not infamous. EA doesnt care one bit about infamous numbers and in reality doesnt compete with it, so it shouldnt care if Sony announced Infamous numbers, really why should EA care anyways?. 

That's across all 3 platforms, right? 

You're confusing press releases with sales numbers (Public Relations) with earnings reports (Investor Relations). This thread is only about the first one.

Even though EA published it, Microsoft is de facto in control of the game and has the most to gain/lose from a release of numbers.

Thats ridiculous, in what way is MS in control of the game? The only thing they control is marketing and servers. EA owns Titanfall and they are the ones who have the power to announce their quarterly earnings. Just because Sony brags every million of everything doesn't mean everyone does it too.
