The next two (2) seasons to be updated will be a new cps1923 and a dps1944. Right now I have no target date other than perhaps by the end of 2017. And in case anyone cares, updating or creating a new season is not done by "many" as a previous post suggested. It is done by myself with the help of a sabermatrician for testing. That tester also has a full time job as a chemical quality control scientist as well as a family. So the process moves at the speed of the aforementioned parties availability (including at the tail end Luke and David).
A new cps season requires more time and effort because much of it needs to be input manually. A updated dps season is actually a new season built from scratch. Virtually nothing from the previous cps version of the updated season is retained. And of course there is the research. Add all of the factors up and I usually estimate between 4 to 6 months for a season to be completed.
