The US Garmin website lists the large MK3i at $100 more than the MK2i.
In Sweden Mk3i is roughly 28% more expensive than the Mk2i. In the Euro zone it is roughly 18% more expensive. While the $100 extra in the US is about 7%.Yes, I was just comparing the watch-only MSRP in the US, which is a $100 difference.
I think it's mainly a question of the US dollar being more expensive now. When the Mk2i was released the dollar was cheaper and the the price reflects that old exchange rate. The price of the Mk3i likely reflects the current exchange rate.
