[AB] TELUS Highspeed Internet 75 soon???

Hi Folks, I got my HiSpeed Internet 50 (50/10) (see review here »[ALL] Telus Internet 50 experience) 2 weeks ago. When I was talking to the tech (had a small issue, see review), I asked him, if TELUS had anything faster than 50. The quick reply was "No". However, I asked him, if TELUS was testing something faster at the moment, and he said, that TELUS is testing a 75 Mbps line at the moment and should be available sometimes in 2013 ... To all TELUS techs in this forum, how long is the test going on already and is is pure fiber (GPON) or is it possible to get that over copper? Is there a better ETA than "This year" like "Q2 of 2013" or so??? Thanks.
