It's the biggest hardware launch in an age! The modem is priced very nicely as well and costs a lot less than an average DOCSIS 3.1 cable modem. You can also follow PCguide.com on our social channels and interact with the team there. Ya, I think it'll be awhile but it just goes to show at some point they'll likely weigh the costs between widening the return path or cleaning it up enough to use higher modulations or just going to fiber when the time comes.
