The reprint has been delayed, from an initial street date around June 2016, to somewhere more around September 2016 (or maybe even October) from the last news I read on the subject. That's is probably why you don't see it anywhere for pre-order as it is the same here in Canada (only one place offer it for pre-order that I am aware of). So I think you'll still have to wait a bit.
According to Rebel.pl, Polish edition is expected to reach the stores later in September. For most games they are producing all the prints together, so I guess the English/international one will be available around the same date.
