Borderlands 4 has four confirmed new characters but who are they?

I didn’t like that they didn’t add any new classes to Borderlands 3. That ensured that I never bought any of the DLC.

Pitchford said not enough people were using the new classes, but I had a great time with Mechromancer and Psycho. Maybe bc I Platinumed BL2 on 3 different platforms.

I hope Borderlands 4 adds new classes post-launch and doesn’t just limit it to 4 again.
