PlayStation is expanding its streaming footprint one piledriver at a time with the new Live Events Viewer. Announced at E3 and available today, the app will let you buy and watch pay-per-view events -- starting with this Sunday's WWE SummerSlam -- directly from your PS3 without the need for a cable subscription. Sony is promising that new programming will be available on a weekly basis and that there will be free content in addition to PPVs, too. All that's available right now are UFC and WWE specials, but according to the US PlayStation Blog, concerts, races and "other entertainment events" are en route. You could also get your scripted and unscripted fisticuffs fix on the Xbox 360, but you need an active Xbox Live Gold subscription to use them.
