Just googled Kazakh visa & clicked the news tab & there's a couple of articles (Moscow times as mentioned and tengrinews) seeming to back this up.
Kyrgyz & Tajik parliaments have passed the laws (waiting presidents to sign). Kyrgyz govt reckon the increased tourist spend will outweigh loss of consular fees.
Kazakh one is a trial period for citizens of OECD countries to see if it boosts tourism (90 day visa free for tourists only). Plan is for it to come in 1st July though not set in stone.
Let's hope so
