To add to that Superchunk the next gen for tegra and snapdragon, as in after Q1 2013 is anyones guess, since that information hasnt been revealed yet. Unless you want to trust nvidias proclaimed advancements for their next tegra device...but only a stupid person would do that.
Its not like a manufactures is going to come out with something amazing for the remainder of this year, the tec is already known, its already planned for release and it is not better than PSV :)
Even a new galaxy S3/iphone 5 is limited to what the manufactures have available for the 2012/2013 timeframe.
