The 7120 is intriguing, but I haven't been able to figure out why they've discontinued it (which is why the price is so rock-bottom cool). It's doubtful that you'd see any firmware updates for it. On the one hand, the 7120 has more power and a potentially more robust platform. On the other hand, the 1070 has better bass management (both digital and analog domains), DVI switching, and better customer support. It's a tough call, and I don't know quite what I'd recommend.
