League Pass on 360 sucked last year. I got an AppleTV for Christmas, and from that point forward I used it for my League Pass viewing. And yeah, if you're gonna get Broadband, you might as well get TV & Broadband, as they're the same exact price (which is ridiculous). For me (TIme Warner), there's I believe a whopping 1 channel in HD, which is horseshyt, so I mainly use Broadband to watch, though usually you get the good late game in HD, so it's good from that aspect.
Regardless, if you're too stubborn to get a Roku or AppleTV, and basing your whole Next Gen experience on if it has League Pass or not, then I don't know what to tell you.
