Hi Roshni,
While we do have plans for a verbal Official Guide companion, we don't have any immediate launch date scheduled.
The earlier post you saw may have been referring a new book we are releasing this month called Foundations of GMAT Verbal, a refresher of the basic verbal concepts tested on the GMAT.
Alternatively, the post may have been referring to a new resource we recently launched called the OG Archer, an online interface for answering OG problems and measuring your performance.
