Call us cynical, but these problems do not need to be solved to market and sell a game. Screenshots do not reveal the average frames per second, pre-rendered video will never demonstrate how poorly the enemy performs in combat -- many of the issues 1UP observe are talking points in developer interviews, but the media and public does not get a glimpse into these games usually until late in the development cycle. While this gives developers time to tweak and fine tune the product, they have already generated hype for their title -- an invaluable asset that moves units and grants consumers the ability to overlook glaring technical deficiencies.
As for sloppy ports, one need only to remember the phrase "screenshots taken from the [best-looking] version." You will see it in almost every advertisement for a multiplatform title.
