According to the Insider, it's because the they are waiting for the anniversary event to release some major discounts. Discounts on all tanks are planned, included premium, plus WG expects a large purchase revenue for the Japanese Tiger (the feedback of that tank on the RU server has been overwhelmingly positive, to the point that they (the players) fear a nerf may come to it.

Basically, the NA discounts aren't so grand as it was originally planned, because the 9.9 release date is coming with a major sale and with the anniversary on the way (not to mention the Kanonenjagdpanzer is being positively reviewed as well).

30% discount on all other American premiums
30% discount on American tiers vi-vii
50% discount on tiers II-V
