Have you considered that they are dealing with unoptimized games and they might be just brute forcing them with processing power?
No need to consider that for my PC developers, Or Sony's developers, and even nintendo's developers. Brute force isn't a videocard capable of displaying images in a way that your console could never display. Sorry, but I don't have to make up shit solely for microsofts benefit. Feels better this way.
These sort of ideas don't need to happen for everyone outside of Microsoft. Others build a game, show the game, game sometimes crashes, it gets released. Thats been happening for generations. Every single statement about the XBONE processing/power/cloud is rendered null and void when they are running game builds without any of it, and it allegedly looks great(according to all the previews). It means all of it is still unseen.
Again, these are all -100 dollars more expensive behind a DRM wall with 24 hour online requirements- problems, but you'd figure for what we know, Microsoft would consider it paramount to show off their wonder device, actually working in ways to justify the pricedrmonline.
It will be seen as more avoidance, as its not done by anyone else. As usual.
