Now, this isn't saying PA is going to suck, but rather that I don't think we know much more about how it, or Wasteland 2, will actually play than we do about Project Eternity. What we saw looks cool, but don't confuse that with actual gameplay.
What we saw was coreographed, of course, but it was much more than what many (if not most) KS projects show. This, combined with the previous TA/SupCom experience, gives us a much clearer idea of what gameplay will be like than the "we have an idea"/"we have a setting"/"we have a brand name" type of KS project, or, at least, it gives me a much cleared idea of what gameplay will be like.
And why do you think that indies right now are minuscule? There's been a huge shift happening over the past ten years towards indie games and smaller studios, and I think supporting that is going to be much more important than supporting larger development studios on Kickstarter. Again, that doesn't mean I think Kickstarter is bad - hell, I think it can be great for smaller developers that already have something to show, and not bad for some (trustworthy) larger ones with just ideas. But seeing Kickstarter as the only way to get away from AAA publishers seems incredibly myopic.
I'm not saying that the indie games environment, as a whole, is minuscule. You are right to say that in the last few years (I would say at least since 2007-2008), the indies have become a significant force when considered as a whole. However, very few of them were break out hits that gained widespread fame. Another issue is that, lately (last couple of years), a lot of indies have started to become dependent on Steam, which is just escaping the gatekeepers that were the old-school publishers and getting captured by the new-style gatekeeper that is Steam.
Both these issues can be traced back to the indies' lack of funds. The lack of funds mean that they need to get to market as soon as possible, which, most of the time means lack of polish, lack of content etc., all of which can put off potential customers. The dependence of Steam has financial reasons too: many indies, if they don't make it on Steam, they are unable to get customers because a huge number of hipsters do all their gaming on Steam, so, if it's not on Steam, they won't even consider the game.
In this context, I see KS (and crowd-funding in general) as the next evolutionary step of the indie game development world. With crowd-funding, the indie developers can get the necessary funds to realize their vision while not having to hurry too much and make a hash of it. Also, with crowd-funding, the indies don't have to worry anymore with breaking even, so they can have more independence from Steam and other gatekeepers. This doesn't mean that all of them can convince enough people to fund them on crowd-sourcing platforms, or that all of them should even try going that route. KS is just another option, a very powerful option, mind you, if they can pull it off, but still just an option.
P.S. I think that Steam Greenlight is a direct reaction to KS, and it's a subtle way of saying "Fuck you!" to the indies. Until the KS revolution, a lot, if not most, of the games on Steam were indies, and which game made it on Steam and which didn't was entirely up to Valve. Basically, Valve had the power of life and death over the vast majority of indies because they were well aware that the indies on Steam were making orders of magnitude more money than most of those who weren't. When KS exploded into the headlines, Steam lost most of that power over the indies. At that point, I suppose Gaben (or some bean counter) said something along the lines "Now that they don't depend on us anymore, why waste all those resources going through all that shit being submitted for review? Fuck them! Let's automate or outsource the process someway.". The result of that is Greenlight. Now all non-publisher backed games (i.e. all non-AAA games) have to go through Greenlight, no way around it, and Valve just gets to pick the ones that have the potential of selling a lot, which now is much easier to estimate by way of Greenlight. This loss of influence is, probably, one of the reasons Valve is now trying to expand in other directions, like Steam for Linux, Steam on the TV, Steam periperhals etc.
