I have tried and tested over 25 suitcases; is this the future...

I have a suitcase problem. I keep testing them. At this point, I have used more than 25 suitcases, across price points, brands and sizes, and I have become annoyingly particular about what I want from one. I like hard cases. I like the structure, the protection and the fact that I can pack everything properly without the suitcase slowly changing shape as I fill it. But I miss one thing. The extra bit of space you get with a soft suitcase.
