If we want to stick with that analagy, I think it's probably reasonable to say that most car manufacturers communicate the specs and differences between models some way in advance of launching them.
But regardless, the analagy is actually inappropriate because this is software and is totally different to new cars. People already have licenses and packages are highly likely to be planning to move to the new version which has been trailed for over a year now, and is apparently only a matter of weeks or a couple of months away. Now is the point many want to plan, discuss things with their teams, their communities etc, but they can't because there's no clarity over which of the newer, more exciting features they may or may not have access to.
The irony never escapes me that Invision, a community building company are so bad at actually communicating - you'd think that would be a prerequisite in this business. I'm sure Invision are trying to create as much buzz as possible about the upcoming version, yet here we are across several threads where confusion reigns (again) due to the lack of transparency.
If Invision really haven't figured out what package will have what features at this point, then that's a failure of organisation on top of the failure in communication. But anyway, it's only been 20 odd years, there's still time to learn how to communicate yet - maybe v10 will have a perfect launch. 🫣
