He did not mention anything about graphical improvments did he? He just said there are a few graphical glitches here and there didn't he? Do you think that is just because he just didn't mention it or do you think that they are done with that?

There was only like 30 seconds during that whole thing where there was not swarms of voices and shooting going on that is awesome.

EDIT: He just basically said that it is a work in progress.
