I DO think it was planned to show the titans, and I kinda think it was a move with hopes to appealing to the GoW crowd. I mean, you gotta think of it like this, there are four titans, and they basically already showed two of them. What about most of the other non-titan bosses. We haven't really seen that Karusaman-bird creature since one of the earlier trailers, nor many other bosses(it's kinda hard to distinguish some of the bosses from some of the enemies, because there ARE some big ass enemies). Maybe that ogre we've seen, is a boss(non-titan boss), but I can't recall any others. Most of the others monsters we've seen so far seem to be normal enemies. Of course, i'm not asking to see EVERY single boss, but choosing to release the pictures of the titans DOES seem to be like them trying to play off the GoW comparisons. And while there will be a few who say, "Ah, it's copying GoW!!", I think there might be MORE who say, "Cool, big, awesome looking monsters.... just like GoW..... I MUST BUY THIS GAME!!".
