Looks like the Google plan is already having a desirable effect, TWC realizes it will have to upgrade to remain competitive. But if Google offers Gigabit at the same price point as TWC's 100 down/ 5 up @ $99 a month, it will be no contest.
But think about the bundle discounts! Is Google going to offer you $10/month off on your bill if you bundle overpriced TV service with them? Huh? Will they?!?
