The information update from Capcom states that they are planning another batch beta testing for the CFN.
The blog also states that the next Street Fighter V DLC character for season 2 is scheduled to go live by the end of April. Dates for the additional testing also remains undisclosed but the new DLC character will playable during the test.
Details of the upcoming DLC character remains undisclosed for now. However, with the resurrection of the classic Thailand stage, it may be safe to speculate that it could either be one of the Muay Thai fighters
(Adon or Sagat) of the series. It was also stated that the new character was "developed under the new CFN infrastructure," which means that the final balance changes
and the new character's launch will be dependent on the stability of the new CFN. Hopefully, it will go live on the given schedule.
