Running on Sunside Inc's in-house platform, Crow looks spectacular for an iOS title. I'm not really sure what is going on in this trailer, other than that you are a crow and that there's some gameplay that is reminiscent of the surprisingly solid Legend of the Guardians: Owls of Ga'Hoole game.
Graphics of iOS games in particular seem to be making quick strides, so it's going to be an interesting couple of years to see how it will all pan out. I wouldn't be surprised to see something like Crow end up on the PlayStation Vita's downloadable space, provided it's actually any fun to play. We'll know if it is in Winter 2011.
