I may get the NBA league pass for the ATV2 (big maybe), but the Netflix 5.1 is very enticing. Only problem is there isn't enough content that plays HD. My biggest concern is 'if' I do upgrade, then XBMC will stop working. But then again, I'm sure Netflix will update their HD content with 5.1 DD sound. I'm tempted to upgrade to the new OS like most people.... hmm.
