That's the thing, everyone has different things that they want. Some want higher bus speeds but consider the current CPU speeds and RAM to be sufficient. Others need more CPU, but don't need the RAM. Still others would like to have more RAM, but don't necessarily need dramatically faster processors. I don't see how the Pi Foundation can cater to all of them. Although, I do expect the Pi 4 next year to address at least some of them. In the mean time, there are great devices, like the RockPro64.
