The next generation keyboard (I'm guessing) will be a sealed set of raised keys that uses the taptic engine to simulate a keypress, similar to how the touchpads on MacBooks work now. This will be a good change because not only will it fix the issues of dust and crumbs and outright key failure, but it could also provide some protection against small spills onto the keyboard.
I just purchased a 2018 MacBook Pro and I actually kind of enjoy using the keyboard, but I'm worried about keyboard failures in the future, and on a $2500 laptop I shouldn't have to worry about that. I'm considering returning it and waiting for a 2019 model with a redesigned keyboard, but I haven't completely decided yet...and it's possible that Apple will just refresh the 2019 MacBooks with new processors, and not address the keyboard issues this year.
