MB8611 upstream speed on new Xfinity 10G network?

I got an email for Xfinity that I have to replace my modem to get the new upload speeds available Xfinity 10G network. However, the MB8611 is supposed to support Docsis 3.1 OFDMA upstream already, so before spending money on a new modem I'm wondering if anyone a MB8611 working with the new faster Docsis 3.1 upstream speed? My download speeds are fine.

MB8611 Upstream specs
• Data Rate:
Up to 800 Mbps*
• Bonded Channels:
Up to 8 SCQAM (DOCSIS 3.0) or
2 OFDMA (DOCSIS 3.1) 

My Upstream status in modem - no OFDMA channels:

Channel Lock Status Channel Type Channel ID Symb. Rate (Ksym/sec) Freq. (MHz) Pwr (dBmV)
   1 Locked SC-QAM 1 5120 16.4 50.0
   2 Locked SC-QAM 2 5120 22.8 50.3
   3 Locked SC-QAM 3 5120 29.2 51.3
   4 Locked SC-QAM 4 5120 35.6 51.5
