Android Phones are underapreciated i see. (even though the IOS games are quite better, and theres more of them. but i think a lot will also come for Android, just look at Dead Space. o: !)
.. the thing is both 3DS and Vita NEED a lot of smaller 5> games in the respective stores to succeed, aswell as 20-40€/$ Games in order to set themselfes apart from Phones, since the latter simply bashes the 2 Handhelds in almost everything else.
