you had to bring in your disdain of consoles to this thread. okay.
as usual, you are generalizing a lot of things. we all know uc4 at psx was live gameplay and not some bullshot prerender running on multiple systems, and pubs differ with the way they handle stuff like promotions.
as of recently and as far as i have observed, activision games and mgs5 do not do "misleading" content on press conferences. the most suspect is ubisoft for watch_dogs and asscreed unity. ea has been a hit or miss, sometimes they will show bullshot sometimes they don't. even then, they do pc shots on their conference and have people play on pc. 2k also doesn't care about those things you so mention. last time i checked, their nba 2k vids on playstation's e3 were running on ps4.
basically, you're just trying to bait people. overwhelming majority don't do "supersampled, blah blah blah" stuff you keep on parading about. that batman footage last e3 looks to be like the batman playstation footage as of late, so in essence that was their target graphics on a completed ps4 build, which they can't produce more than a year out, but they have basically met those targets now.
