Differences Between C-5 and C-7?

It's always fun to speculate and see what exactly happens down the road. I can understand wanting to keep things pretty quiet. Now, just throwing it out there... I can't help but notice that the only version of C-5 currently available is for US/Canada. I'm going to "assume" the versions for Europe, UK/IRL and AUS/NZ were available at some point since they are all listed on the Hubitat Store. Keep in mind, I'm new here so don't know the history for certain. Makes one question if there's another reason none of these three options are in stock... say, selling off the existing supply before release? :thinking:
