Cubase only supports up to 96. You need Nuendo if you want any higher with Steinberg seqs. TBH tho, if you can hear a difference between 96 and higher then you have hearing pretty much no one else on the planet does. Even more so youll need an exceptionally capable pc (quad core or better) to run even a single vsti at 192 without audio glitches.
Forget 192, manufacture hype. You know the vast majority is still done at 44. You'd be hard pressed to notice a difference from vstis at 44 and 96 in a mix, and thats listening out for it. The average listener (99% of people) couldn't tell the difference and couldn't care
