Quote - And there is a very important realism feature coming that nobody mentioned lately but I named it as my #1 desire last year and its here. Oww - my tongue.

the only thing that your number 1 could be in 2008 is SSS. but i think you said it wont be there.

the other thing you said you want is to make your own nodes inside the material room. but thats not an realism feature.
maybe something about the lighting but i think everything was mentioned here.
