Yes - it's the appearance of hardware like that that makes me suspect BT might include this technology in trials this summer, combined with the rumour that vectoring deployment could be stalled.
I have no more evidence than BT's statement that their target is "initial speeds of a few hundred megabits" before aiming at 500Mbps in the longer term.
Deploying hardware that is powerful enough to run G.fast in the long-term, but starts out running "just" profile 35b in the near term, might fit with BT's announcements. It could be a better decision than just rolling out 17a-vectoring linecards.
