This article is completely stupid. The whole point of Kickstarter is to sell a dream. 9 months (not 8) is plenty of time to get the pieces in place. And you know what? It'll probably slip a few months. Big deal. The entire article is chock full of FUD. Why not give the company a few weeks or months to make some visible progress before trying to squash the enthusiasm. Donators are only in for $99 so it's not like anyone's going bankrupt over it.
I don't think the article's intention is to convince people it's a con or crush the enthusiasm. Their points aren't illegitimate and their arguments are fair - isn't it prudent to criticise them and see how they respond rather than let them continue unchallenged, especially considering the collective financial contribution involved?
Considering that they already have prototypes together, they've already apparently got something to show. As the article points out there are flaws with what they're offering and questions that need answering.
I'm sure most of the questions and queries can be answered satisfactorily, but the crux is the lack of confirmed titles, which they can't fix themselves.
I think they should really have already got something cast iron in the pipeline from some reasonable sized developers (mojang for example) before they launched the kickstarter.
Has anyone ever released a console without at least a few games in the pipe? It never turns out well when there are very few games, but 9 months from release they don't have any games.
