What does super-bandwidth mean for PC gamers?

I'm very satisfied with my home DSL connection's top speed of six megabits per second (Mbps). I can download games off of Steam in a few hours, stream Netflix in HD, and generally enjoy all the best of what the internet has to offer.

Satisfied, that is, until I see something like this: Engadget has posted evidence that Comcast may begin offering insanely fast 105Mbps connections in the very near future. It's not cheap—the asking price is $200 per month, and that's after the $250 installation fee and another expense for the specialized cable modem purchase—but can you imagine what it'll be like for gamers when that kind of speed comes down to consumer-level pricing?
