No one cares because it isn't really needed
Seriously, Qualcomm's first gen / test 5G chip can do 5 gigabits - what's the use case for that in a phone or tablet? Or even your home internet connection? There is none, because even Blu Ray quality 4K video is 100 Mbps at the most. Even if you are streaming a half dozen streams to your whole family you don't need 5G.
Visual media is the richest and densest sensory input humans are capable of, we've gone from text to audio to video and with 4K are taking video about as high as we can. OK maybe in a decade once everyone has bought a 4K TV they'll start pushing 8K, but at some point people will just stop caring because no one can tell the difference.
We haven't even come close to hitting the limits LTE offers us. The LTE most of us can get where we live is less than 10% of the maximum speed it is capable of, and when you're getting 40 Mbps on your phone most of us aren't bitching and moaning about why it isn't 100 Mbps, let alone 1 Gbps.
I think 5G with its crazy 28 Ghz and 60-70 GHz bands will have two main uses. One, fixed wireless for home internet - LOS restrictions aren't a problem if it just needs to get to an antenna connected outside your window or on your roof. Of course at those frequencies you will lose internet when it rains really hard... Two, large open gatherings like stadiums, concerts, etc. where you temporarily have a ton of people in a small area without obstructions, and need to supplement the normally available cellular infrastructure.
