"We break things. Julie Uhrman has been in games for a long time, at Vivendi Universal, IGN, GameFly, and other places. Yves Behar is the award-winning designer of Jambox, One Laptop per Child, and many others. There are plenty of other people involved, but some of them would get fired if we tell you who they are."
Julie Uhrman is an executive (http://www.linkedin.com/in/julieuhrman). Yves Behar is a designer (http://en.wikipedia.org/wiki/Yves_B%C3%A9har). Until I hear about the involvement of at least one full-time electrical engineer and embedded software developer, I'll be highly skeptical that they can deliver anything that they promise.
Especially in the time frame cited; I've worked in both fields and unless they have experienced full-time engineers and developers working on this right now there's no way they're making the deadline. The "we have a prototype" is at best a vague indicator of progress. Do they have a board designed? Has it been fabricated? Do they even have android running on the hardware they plan on using?
If not, are they using off-the-shelf boards? I can't find any Tegra 2 OTS boards available remotely within the price point they list, much less Tegra 3.
And the "some of them would get fired if we tell you who they are" is more disconcerting than assuring. If they do have people with engineering/manufacturing/software development expertise these people do not believe in this project enough to leave their day job. That should speak for itself.
EDIT: for example, see http://trimslice.com/web/order-direct. Their Tegra 2 board with more modest hardware specifications is only available at more than twice the price point touted for Ouya. Note that this doesn't even include the cost of the custom bundled controller, which is itself a substantial hardware undertaking.
Concept design and manufacturing are completely different things. I'm talking about manufacturing experience, and they have none. Zero. You can be sure they'd have mentioned it if they did. Let me address their only revealed experience: "Vivendi Universal, IGN, GameFly," those are all 100% software. "[They] would get fired if we tell you who they are", really? They're asking for millions of our dollars and they aren't confident enough to even minimally risk their current jobs by publicly supporting their own project? That's a huge red flag.
The console industry is littered with spectacular failures of this type, and I'm before I believe this one is worth investing actual money in I'm going to need more than Yves Behar, Julie Uhrman who's "been in the game industry for years" (exclusively on the software side), and several mysterious people who refuse to even be named.
Sounds like they have hardware experience
