Ace Combat Infinity Only on PS3?

Ace Combat Infinity got its first trailer recently. When they say teaser, they really mean it, this 46 second teaser gives us the line:

That day out sky fe||, the heavens split to create new skies.

It then shows a…polygon? Not sure what it is aside from a shape, falling toward a digital representation of Earth.

Many flashing screen of planes, land, water and what could be internal components to a plane becomes the logo for the game. The last shot is the belly of a plane, swooping toward a city.

The closing screen shows:

For PlayStation 3 system.

So now I ask–will it be only for PS3, or will it come to others later? Your thoughts in the comments bellow.

Namco Bandai have said that the game will be a downloadable games for the PS3 store, but have not said if it is exclusive or not, and there are more details to follow.

What do you think of all this? Is downloadable good or bad? Could this be a Free-to-Play Ace Combat game? Speculate in the comments.

For now we can only wait.
