Right near the end of the Coventry trial I was given a modem with 8 bonded channels down and 2 up. It was regarded as a proof of concept trial rather than 400Mb. I achieved an average of 360Mb down and a consistent 24Mb up. This was consistent with the maximum settings of the modem. This and the 200Mb trial were, of course, on a trial circuit and using a 1Gb pipe. The 10Gb pipe VM had in reserve, in case the trialists overcooked it, was not needed.
The techie in charge, who is now conducting the 1.5Gb trials, said that the 200Mb and 'proof of concept trial' opened the way for commercial speeds of 200Mb and 400Mb. How this is to be done with all the issues frequently discussed here, I do not know. He gave no timetable partly because he didn't have one.
One thing is for sure, I had to upgraded my processor to a quad core to hit those speeds consistently in tests! (I was upgrading anyway.) My router, a WNDR3700, was more than capable.
Here's a typical result:

This is the best I could get from speedtest.net
