I'm at a loss as to why people seem to think they are entitled to be given extended video footage of an unreleased product almost a year ahead of the expected release date.
They've created huge buzz with the likes of Game Informer, E3, VGX and the various interviews in between. They are constantly in the top 2 of most anticipated games, and one of the larger sites, can't remember the name, was so excited for it they had already put up a mock review of the game.
Marketing dollars are not unlimited, marketing has to be tactical, and it's best to have your marketing push closest to the release date, and demonstrate it in detail and in a big way, when all if not most of your best features have been implemented in the game.
We do not know what CDPR have to show off, we have only seen pretty graphics, they are probably still tweaking game mechanics, motion capture, dialog system, enemy AI and who knows what else they have yet to reveal.
Be patient Danielson, more is coming most definitely.
