Battlefield 3 on the console, somewhat dissapointing?

I know that the Battlefield series was on the PC first before consoles and that PC`s can continuously update their software for better experiences, but when they showed the PS3 gameplay of the game on that late night show, I was kinda disappointed. The smoke didn`t look as realistic, like it was going through materials instead of growing. Plus the M16 didnt even have an ACOG on it. I think I even noticed some diferent level design in places. I know what DICE meant when they said that they can`t just upgrade a console because it came out five years ago, but why did they show the PC footage when people would expect all three platforms to look the same. Most people know that they`re largest community is on PC, and I can respect that, but I don`t think DICE realizes how many console gamers have seen the Fault Line gameplay that they released. I was hoping for the same amazing experience that DICE has been promising from the beginning, but now Im disappointed that I may not get the same quality game. Why did DICE wait until now to tell people that they just couldn`t make the same game for console? I know I`m not the only one upset about this, as many sites have been posted talking about the graphics quality. Does anyone believe that maybe DICE is working on this, even though they probably arent?
