When will V4 be discontinued?

[weilin]

When V5 was released in 2018 for the Turning Point season they were talking about Cortex being legal for the next 2-3 years.

V5 replacing VRC?

Just a statement about the terminology being used. VRC is not being replaced. VRC stands for VEX Robotics Competition. It is the name for the Competitions that we enter. VEX EDR is the name of the robotics platform that we use and that is not being replaced. What is being replaced is the brain (processor) that runs the robot, the controller (that the drivers use) and the motors, batteries, and ultimately the sensors. You will not need to buy new Cortexes as the Cortex will be phased out. …

Normally you would expect that it will not be legal for the next season, but because of COVID they could extend it for one more season, I think.
