They go on to say that the projected launch date for KU in Brazil is early 2015, which I would be willing to bet is overly optimistic. Amazon missed several rumored launch dates before finally launching the Kindle Store in Brazil in December 2012, and I would expect that Kindle Unlimited will face similar issues.
Amazon isn't talking about their plans for Kindle Unlimited, but my best guess is that Amazon will only launch KU in a market where they have managed to secure a minimum number of local titles. This could explain why Amazon launched KU in Spain and Italy a couple weeks ago, but not anywhere else in Europe, and why KU is available in the US and UK but not Canada, Australia, or NZ.
If and when Kindle Unlimited does launch in Brazil, it will face competition in the ebook subscription market from Scribd, which is available globally, and Nuvem de Livros, which is native to Brazil, has been operating there for several years now, and possibly has an even a larger subscriber base than KU, Scribd, or Oyster (no one is talking, so we don't know).
According to one report, Amazon has 40% of the Brazilian retail ebook market, which accounted for under 10% of the total book market in that country. Amazon's competitor's in Brazil include local booksellers as well as iBooks, Kobo, and Google,
Kindle Unlimited is currently available in the US and 4 countries in Europe. Subscribers pay $10/€10 per month to read as many ebooks as they like from a catalog of around 750,000 titles.
