1 brand might be good. Instead of HSI for internet and CDV for Comcast VOIP, an Xfinity brand could be used to market against Verizon & AT&T and their product suites. But I don't think existing customers will care. This is probably about marketing campaigns to other companies customers.
Now that Comcast is also going for quadruple play opportunities by adding wireless cell access, I guess we will hear about Xfinity Wireless as well.
