Don't Wait for a 16-inch MacBook Pro Yet
Apple announced the MacBook Pro 16 in November 2019, and it's unlikely that Apple will release a new model until the fall.
If you want this larger model, which replaced the 15-inch completely, you should simply purchase one now. We're already seeing a number of 16-inch MacBook Pro deals that offer hundreds in savings depending on the model you want.
This may seem counterintuitive since we are suggesting you may want to wait for the 14-inch model, but there is already a very good 16-inch MacBook Pro for sale today. It is too early for most buyers to start waiting for the 2020 MacBook Pro 16. Some users will want to hold off, but the majority are OK to buy now.
