Lakshya was brought in to help with the expanded scope in NPCs and characters. I seem to recall a small snippet where the development team has increased.
It could be larger than we think now.
The Shenmue 3 Lakysha team consists of approximately 30 game artists, namely 3D character art. In Japan I would estimate another 50-55 staff comprised primarily from YSNEt and Neilo staff, as well as various local contractors. This would would bring the team size to approximately 80-85 members, far smaller than the 175 member Shenmue 2 team, but still very capable at that. As an example, the highly acclaimed Shadow of the Colossus PS4 remake was achieved by a team of 80 staff spread between Bluepoint Studios and SIE Japan Studio.
As far quality is concerned, my sense from Yu Suzuki based on past interviews is that Shenmue 3 will be his most personal and intimate game in the series. I believe that we are in for something quite special.
