According to this video Nokia announced that the n9 will be available in Brazil in September.
The bloggers who recorded the video "guesstimate" that it's going to cost 1500 BRL (670 EUR / 960 USD), which is the same price that the n8 had when it was released in Brazil.

According to the Nokia Brasil website, both the 16 Gb and the 64 Gb and the three colors will be available.

Since Brazil is always one of the last countries to get the best Nokia phones, I believe the rumors about the n9 being released in Europe in August must be true.
