Thank you for the response.  I have followed the instructions to DM Xfinity Support.

Thank you to XFinity support for the responses.   The  answers I received are:

• The Gigabit X2 Internet tier that provides up to 2 Gbps, requires an Xfinity Modem. 
• At this time support has no information as to if or when any customer will be able to use their own modem for the 2 Gbps internet tier.

I further responded that I personally saw this as a poor business-driven decision and not a technical one.  For the 2 Gbps tier the cost are as follows:

• $120.00/mo Internet service
• $15.00/mo for the xFi Gateway.  (There is another option for $20.00/promotion that increases to $25.00/mo after 12 months which includes faster upload speeds.)

So the minimum charge for me would be $135/mo for the 2 Gbps.  I live in the 02142 zip code.  I will not upgrade with this requirement in place and seek other options that emerged in last 12 months in my area.

Just went through this same thing but I did use their equipment and it was false advertising for me. Now I need to go back to store and explain that the 2k download never existed and even had a technician come out to say the same thing .  Let me know if any questions I will go in further detail going to make a Reddit post about and link here later

here is my update post on this 

So yesterday I get an email saying I can upgrade to 2000mb internet. I also have the nighthawk cm2000 which states I’ll be able to get speeds surpassing 2000mb. Once I made the change my internet wasn’t working. Called customer support and I had to revert back to 1200mb. I tried looking up modems that support it but they aren’t even being sold in the market yet. Xfinity listed modems in the email that support their speeds but they aren’t even being sold yet. I see it as they want you to rent their modems. I’ll just wait until the cm3000 is released. Renting a modem at $15 a month is the worst thing to do…
