They weren't promises but development targets and industry rumours which most devs don't even have the balls to say to the public.

I don't ever think they said anything about 20 hours, or the stupid sixaxis functionality (which has rare cases of being useful or good, Heavy Rain, Killzone 2).

I don't care about the 1080p as this game looks damn amazing and they probably couldn't have made it look as good in 1080p.
