If your on one single channel then no not till D3 is officially launched in your market there won't be a whole lot of difference. That same package though that I have here requires a D3 modem since it will be changed to 30/5 when D3 is officially launched here.
The reason why I purchased the modem wasn't because I wanted a better QOS, but because I had to get a replacement modem and I thought it would be best to get a docsis 3 modem for future-proof. However, if I would have known that my speedboost would have been taken away, I would have went with something a lot cheaper in price. Very disappointing news. Wish I would have known.
