========================
Murazor confirmed the plans to change the branch
of the T-150>KV-3>KV-4>ST-1>IS-4 tanks.
IS-4 will move to the 9th tier. The changes will be
in the whole branch and the developers think about the introduction of
the ST-II tank, pictured below (multiple variants are considered
apparently). That’s all we know for now.
Murazor 证实了改动自T-150至IS-4科技树的计画
IS-4会降回T9，改动会触及整条线，
另外开发人员在考虑加入ST-II一事，如下图(很显然有考虑过多种衍生车型)
以上为目前所知
*给还没看过ST-II的
