Verify that the Arris S34 supports next-gen (>200mbps) upload in my area

I would like to see if someone from Comcast can confirm that the new Arris S34 modem will work with the newer 200mbps upload speed. Right now I have a Hitron Coda 56 modem that is successfully getting this speed (with overprovisioning it's actually more like 340-350mbps), so I would think that the S34 should work equally well, but with this company you never know..... let me know, thanks.
