I listened to Playstation blog cast today.
It seems that since someone already made a dinosaur mod and ppl are asking for it, they might make official dinosaur horde mode.

Dinosaurs are the new zombies
Wonder if we'll get nazi dinos.haha

The EA man said something along this line "There ARE ppl that asked for it, so we make it and see how it goes."
He also implied that just because some ppl are against it doesnt mean that they arent gonna try to pursue the idea and put it in the market.
He was responding to the large anti-dino sentiment brought by BF3 players on the forums.You can see for yourselves the massive dislikes for videos if you search for anything "BF3 Dinosaur Mode" related.
Haters gonna hate.

Some footage of supposedly dino-leaks...dunno if its true...see for yourself
