I got an answer from CZUB today. Then didn't send any pictures but then I really didn't expect them to but they are going to be short rails as in the '70's but CZ is NOT going to go back to ever making short rails, as an actual production pistol. Her is a copy of the e-mail:
"
Dear Mr Niehaus,
1) The CZ 75 Anniversary is a retro version of the CZ 75 as made in mid-1970s. This model is outfitted with short rails in comparison with current CZ 75 B version.
2) Except for the CZ 75 Anniversary CZUB has no intention to go back to short rails. This return to the roots is merely and only a special edition to the special anniversary having the "75" numeral."
So now it's simply a waiting game untill they come out.
Yours faithfully,
