The game is still half a year from being completed, folks! I don't see the whole point in these graphics discussion at all. We know it's an old, outdated build they showed us; and furthermore we know that it's nowhere near being optimized completely.
Imagine this scenario instead: You go to a guy on the internet and order a cake, because he has some very delicious looking pictures of cakes on his webpage. First everything is fine, but then he sends you a status update on the cake, and the pictures you get from him don't look anything like the ones on his webpage - of course, one could say; despite the fact that all the ingredients are already mixed in, the cake was still unbaked when the photos were taken. So, what would you do? Would you go full suspicion mode or would you wait until you get your hands on the finished cake before you complain about it?
