Big question will be whether the entire library will be available globally.

It was great that Netflix launched internationally, but basically every country has just a fraction of what's offered in the US. In fact, some Netflix-produced shows (such as House of Cards) still aren't available on Netflix in other countries due to licensing agreements (where Netflix licensed the show to a local distributor with exclusive rights before Netflix launched there).

If the entire Amazon Prime library is available in the 200 countries, fantastic. If not, then this is click bait by Amazon, nothing more.
