Answered: Integrated Motor Encoders

So the vexrobotics website says that the new encoders will be connected to the I2C port. The cortex only has one I2C port. Does this mean you can only use 1 new encoder?

No, you can “daisy chain” the encoders together. You plug your 1st encoder into the Cortex, then you plug a 2nd encoder into the 1st one, then a 3rd encoder into the 2nd one… and so on up to (8) I2C devices.
