The Mali-400 on http://www.hardkernel.com/renewal_2011/products/prdt_info.ph... is already posting better benchmarks than the Tegra3 on the Ouya and the CPUs are the same core, this one slightly lower clocked. Sure the price is a bit higher than the Ouya for a dev board, but that's something you can buy right now. And they're only going to be better and cheaper by the time the Ouya hits, which if I might remind is still five months away if everything goes to plan. Might as well be eternity at the rate cellphone hardware evolves.
Really, all they've done is sold a case and gave us some simple interface mockups. Even https://en.wikipedia.org/wiki/List_of_Ouya_software is completely underwhelming and resembles the total lack of commitment other DOA consoles like the NGage had going for them.
You can expect Asia to be cranking out a new Ouya-like every few months. It's the software stack on these devices that is significant, as the hardware is now practically free. Hell, it's even open source: https://www.olimex.com/Products/OLinuXino/ *
(* Mali-400 GPU still not fully reverse engineered. As usual, GPUs are the FOSS barrier -- still, there's hope: http://limadriver.org/)
Maybe there will be Asia clones ones it's out and a success, but so far there aren't. Someone has to be first...
And if it can get even cheaper in the long run with that hardware - that's also not exactly something speaking against it.
You got maybe a point with the games, but even there I'm not too worried. I don't need lots of good titles for a console - give me a handful of fun titles and I'm fine. Even playing supertuxracer on TV would already be enough fun for me to consider getting it :-)
