The limiting factor, is going to be the egress from the Verizon network. Sure, VZ could offer 500Mbit up/down, but what would it look like, when 100,000 people up and down the East coast for instance, try to stream their favorite TV shows & do other Internet stuff all at the same time.. All that traffic has to exit Verizon's network to get to the carrier that hosts that content. Unless there's a way to bond 50 OC192's together between carriers, and/or all carriers upgrade to multi-terrabit backbones, huge bandwidth only spells one thing: massive oversubscription. My original 768/90K DSL connection went to sleep at 5PM, so I went to cable-modem (in ~1999), and it too ended up going to sleep at 5PM. [For now], FiOS doesn't do this... yet(?)
10 gigabit ethernet is the new standard these days with 40 gige and 100gige options as well. You can provide for *a lot* of customers with a single 10 gige link. VZ also balances load between multiple routers.
You can also easily put up to 8 links in a bonded (802.3ad) port-channel/lacp which could easily do 80 gig with 10 gig links. VZ is alter.net which is a tier1 provider. They have *massive* pipelines to all the other tier 1 transit providers (as its required to have settlement free peering with other tier1's to be a tier1 transit provider).
Just to add to this, Verizon has been in the news about its upgrades to 100Gbit between major US cites POPS »insanetek.com/news/1-web-and-ind ··· o-the-us
as well as between the US and Europe »www.v3.co.uk/v3-uk/news/2030549/ ··· k-europe
While I do not know how far along they are on this project it will bring substantial increases in compacity when its done.
Also to the op, Comcast's 305Mbit tier is worthless to most people who want low latency or to actually use that 305Mbit speed since they oversubscribe there main connections to try to force people to peer with them at ridiculous rates. For this all you have to do is look at people bitching about 300-1000ms ping's during peak hours. »tech.slashdot.org/story/10/12/14 ··· y-choice
while this is from 2010 the same crap happens to this day even with Comcast denying the issue. I get people who bitch at my Job on a weekly basis who use Comcast at home and have major problems at night with lag while connecting to our VPN (We have ~40Gbit to Verizon and Cogent both major backbone providers and only Comcast users bitch about lag). To add to this when I asked for a quote for 1Gbit from Comcast (Who has fiber in the building) the price was more then I pay for a single 10Gbit circuit from Verizon and about 2x the cost of Cogent.
