Differences Between U.S. & Canadian Models

Until I joined this site and read many posts, I never really thought that much about how cars were configured differently (standard features and options) outside the U.S.- and why Acura chooses to do this.
It seems that each new model year, Acura will "add" a feature to a car to make it a little better or improved over the previous year's car... For example, I remember with previous TL's, how Acura added the keyless FOB one year as a standard feature not present in the year before's model.
So, when the new 2016 TLX's roll out, I wonder what change or addition there will be over the 2015 models- and if it is likely that we, in the States, will see, for example, a heated steering wheel or folding mirrors as our "bonus"- and people in Canada will see something which is currently a U.S. exclusive??
In other words- is Acura's logic to pull out these features from other places as their "value increased marketing plan" from year-to-year, or generally, when something new is introduced in new model years- it is a brand new concept never before seen from Acura cars produced from other countries??

Is anyone up-to-date with what Acura has done in past years with their cars (what features/options have crept their way over the borders from year to year??)
