Given they have used 2 pics for Drive Club and Killzone, it just looks like they're trying to pad out the PS4 line up so perhaps have added multiplats too.

And the Xbox one has free to play titles. If you actually believe the * means it's multi plat you're kidding yourself. Halo and Project Spark have it also.

I'm not saying Deep Down is confirmed ps4 exclusive but damn come up with better reasoning rofl.

I said perhaps, I don't even know much about Deep down. My point still stands about the need to pad it out though.

Arbeitstitel or "working title" means it is the actual name of the game, but that may change before the release.

No it doesn't. Xbox One has 2 free to play titles. They could have easily included Planetside 2 and Warframe or the many exclusive Indie titles coming to the PS4. 

This is what I'm thinking. I doubt Microsoft will just call it "Halo" when it releases. Would probably confuse some people.

There choices for Xbox One are odd, they could have added Titanfall, Sunset Overdrive, Zoo Tycoon, Dead Rising 3, KSR ..

I do wonder why they put less on the PS4 part.

No. Sony wouldn't pass up the opportunity to state that the game is exclusive.

What game is multi on PS4 side? I know Project Spark is multi.

Well...
