Indeed.
It is indicative of a pattern of behavior that's been with gaming for far too long though. Selling people on impossible to meet standards of visual excellence and performance, only to launch with much weaker, much more down to Earth and flattened results. Its a bait and switch, and its done because whether the end product meets up with those lofty expectations or not, it works. It engenders hype and early press, and hey, maybe people who only saw the reveal and early footage (actually not footage but tech demos, vertical slices, or straight up false-mock demos) don't follow up with the game all the way up to release and end up pre-ordering or buying things they decided on long ago. Or hey, maybe people bought into next gen entirely based upon the promise of those target visuals and gameplay, to come "soon".
For me that's where the disappointment comes. From an understanding that publishers or devs are going to try to pull the wool over our eyes until we see actual final master release footage. Its to be expected, and that's a sad state of affairs to find yourself in. Now to be sure, that's disappointment, not rage, because I *do* follow games throughout their development, and try to keep up to date on this stuff, but I know customers are being fooled, even if those customers don't realize it themselves.
So, no, I won't tell you how to do your job or whats worthy of an article, but if you ask me - that fucked up status quo with early footage is the crux of the disconnect here, that leads to the disappointment and threads and backlash.
