This is sad. The last time we saw a new red lightsaber, was 6 years ago in Force Awakens. And it wasn't even a real Sith lightsaber!!! It was Kylo's lightsaber. 

This was the last time we saw a new red lightsaber. We've had 6 years with no new live-action red lightsaber! But now, finally, we get new ones.

Finally, we get a new red lightsaber! A real one! We've had a lot of new content but no Sith or dark side users. Now we're getting into the lights vs the dark. 

I'm so excited for Kenobi. Along with Reva. we get 5th brother, the Grand Inquisitor and maybe 7th sister. I'm so happy to see a red blade.
