On October 1 for most forms online, October 29 for the other modes including MyClub.
Fans of PES 2016 carried few days asking Konami classic template updates for teams, as the game goes from the 17th of October and are still frankly outdated.
Today Konami has announced its intention to begin the deployment of these data packets in October. Day 1 for most forms online (Quickplay, Divisions On-line competitions and lobbies) to other modes (including MyClub) and some specific equipment such as Galatasaray, APOEL, Maccabi Tel Aviv and Panathinaikos, among others, will have to wait until day 29 of the same month.
Following this link you can take a look at this first Data Pack in detail, but we anticipate that some changes are also included in its statistics and data based on their weekly performance.
