According to Amazon, the books on the T-34 and the SU-152 being put out by World of Tanks have been delayed until summer of 2017. Originally slated for a summer 2016 release, these books were then pushed back to November of 2016. Now it appears the wait will be even longer. These books are hardcover volumes authored by Russian researchers. The SU-152 book is written by Yuri Pasholok and the T-34 book by A. Ulanov. Hopefully this delay is the last one these books will suffer, we have been looking forward to these.
