I know that it had been shown in testing to reach 200 Mb/s - call me when real world usage data can show that kind of result.
In reality, the kind of progress that @barbegal mentions has done more to advance device capabilities, but for something that was initially sold as a 10x speed improvement over 3GPP, it hasn't really panned out.
The telecom folks make a bunch of noise about how you can replace a home connection with these kinds of technologies, but until prices come down and speeds go (way) up, the wireline people don't have much to worry about.
