I cannot say specifically, cause I don't have the details and can only speculate. But I just know one thing, nothing in life is free, you pay for it some way or the other. So if I get 5 years warranty versus 2 years in another country, it probably worked into the deal / price is some way versus their price. And if some countries are getting a bigger discount, then it also a strategic decision in that market. One also have to think about different shipping / logistics cost and import tariffs to different markets, which can make a difference in cost and hence price. A potential lower cost could and possible lower price can be turned into a longer warranty instead of offering a lower price in that market; or vice versa. So for what's it worth, its useful to know, but its not going make any difference in my life. If I want it, I have to take it at the price and with specifications that are offered in my market; and can only compare with available rivals in my market. Its almost similar to what they say - what happens in Vegas, stays in Vegas.
