It's a sorry state of affairs when a media player like the Zune HD has more polygon-pushing power than the latest handheld videogame consoles on the market. If rumors are to be believed, Nintendo and Sony will set things straight with their next-generation portables -- at least for a little while. We've already heard that the successor to Nintendo's DS will have Tegra power, but the current speculation is that it'll be a Tegra 2 chip, promising twice the power of the current iteration. On the Sony side the PSP2 is apparently shaping up to use an offspring of the IMG PowerVR graphics found on the iPhone, said to be theoretically superior to what the DS2 will be able to achieve but costing more, being more difficult to develop for, and not shipping until sometime in 2011 -- potentially a year later than the DS2. In other words it's standard operating procedure if these rumors are to be believed, but even if there aren't any surprises in this showdown we'll be there in the front row with popcorn to watch the bloodshed.
