My analogy was merely meant to highlight how ridiculous it is to even hint at the idea that wine (making a motorcycle instead of a car) was a possibility.
Whether or not it was ever seriously considered, Wine was the only alternative to creating the middleware that didn't exist, short of dropping the Linux version entirely. It isn't ridiculous to say the game is taking longer because Larian is sticking to the original plan, even if it will be harder than expected, rather than switch to 'plan B'.
It is not uncommon in game development (or other creative endeavours with limited resources) for features and/or content and/or platforms to be dropped or changed. Sometimes games have been cancelled outright. Kickstarter makes this process more public, but it doesn't change the process.
