It seems that Samsung Galaxy Note 5 unveiling will be pulled forward with about three weeks or so.
Right not, the company developers priorities are the following regions:
North America,
South Korea,
China,
Singapore,
Hong Kong,
Asia.
Europe and Russia markets may be delayed, for how long we don't know. New York, and whole North America in particular, are Samsung biggest markets, so there is no surpries there.
It would be very interesting to see a 5.7" Galaxy S6 edge Plus announced alongside the Note 5.
