For months tipsters have told us that a 100 Mbps Comcast residential tier is getting very close to launch, with those insiders telling us Comcast would like to hit 20% of their markets with the ultra-fast tier by the end of this year. The looming super tier has been confirmed by some bill insert notifications that began circulating back in June. Light Reading points out that there's flyers making the rounds in Denver that get significantly more specific, the ads promoting an as-yet-unlaunched 105/10 Mbps tier for $199.95 per month (plus a $250 installation fee). Still no word on launch markets or whether that 250 GB cap will apply, and Comcast still won't officially confirm any details to us other than the fact the tier is "coming soon."
