In Canada it seems like we will only get 546 cars over 3 years, so 180 a year for the entire country, which is very low. I don't know what the US numbers are but I've heard the new Type R is going to be at 40% production capacity compared to the last gen. I believe the US received something like 48k Type R's over 4 years for the last gen, so now you may only be getting around 19k over 3 years for the new one.
If you're at the top of a dealer list you will most likely be fine but if you only recently got on a dealer list, depending on the dealer, its possible you might not see one given the assumed limited production run.
