Sure, and I still think throwing money at this at this stage just for that is not a smart use of money. You may disagree and that's fine. Let's say they raise $10 million dollars though. What's that going to do? What value will that add? Where's that going to go?
It’s going to lead to fulfillment of promises for pledges (that should be self-evident), it will add value for the developers who are pitching in for the early devkits and want to have games ready by launch, and having extra capital in a business doesn’t hurt anything—it ramps up production, R&D, marketing, and market expansion if you can’t think of anywhere else to put it. It can also encourage even higher-stakes investors to get in on it if that’s something they’re open to, due to the higher profile that a $10M Kickstarter funding would give the project.
Saying throwing money at this stage at it just for the rewards is not a smart use of money may be true, but it is no less smart than throwing money at video games in general. The people who are funding it think it’s worth it, whatever they’re getting out of it; the people who are getting more money aren’t going to say no. This isn’t a whole lot different from going to a store and purchasing something you want but don’t exactly need. Well, these people want to purchase their name on something, or an icon next to their gaming handle, or a statement about the non-open platforms, or a devkit, etc.
This reminds me of stock market pump and dump schemes and golden parachute Best Buy CEOs. 
Consider the people who are behind this project. Consider the endorsements. Consider that they have everything to lose if they are cheating. They have a very strong ethos here. I don’t think this sort of cynicism is warranted. Criticism, sure; I could list a variety of solid criticisms of what has been shown of this so far. Cynicism, no.
