Simulate the future version

[nosalan]

Question:
I want to display an output that the version is about to be upgraded before running the nbgv prepare-release command.
In order to display it, I need to get somehow the next future version, which for example depends on the version increment being set in the version.json file. Is there a way to get the version that nbgv prepare-release will set in a simulative manner?

No.
What if we added a --what-if switch, which prints the new version but doesn't actually make any changes?
Do you need the output to be machine-readable, or merely human readable?

[nosalan]

--what-if sounds excellent, preferably with the machine-readable output.

Great. We'll keep this issue active in case you or others can prepare the PR.
