Battlefield 3 Fail?

I dont like to say this guys but today while i was watching the Battlefield 3 PS3 footage again I noticed something really really sad or bad, if you watch this video by the minute 1:45 to 1:48 you can see two boxes or generator popping up as you advance to them, and I dont like that at all because who knows what can pop up in the middle of the game or what can pop out. I hope this is just somthing in the Alfa version of the game and not something on the real game.
