That Eurogamer article was pretty worthless. If publishers were interested in making the games that get funded on KS, then developers wouldn't need to use KS. The reality is that publishers are extremely risk averse and if they don't think a game will sell at least 3 million units, they probably aren't going to fund it. That's why niche genres like CRPGs and space sims haven't seen publisher support in years. KS provides a means for such neglected genres to get made without completely forsaking decent production values.
I also love how the article portrays devs like Schafer or Braben as millionaires. Game development is not going to make you rich unless you build a game by yourself and it sells millions of units. If you do contract work (as most developers do), you'll get paid during development and then you'll never see another penny after that unless the game is tremendously successful and the publisher didn't screw you with arbitrary royalty requirements (like minimum Metacritic scores).
